That's an important piece of the performance story, but it's just one - what about once the page has loaded fully? That's when users want pages to animate smoothly and react quickly to their scrolls and clicks. Chrome 41 included a task scheduler for Chrome's rendering engine that ensures those high-priority tasks are handled immediately, making Chrome feel snappier and run closer to a smooth 60 frames per second.</span></div> <div dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"> <span style="font-family: Arial; font-size: 13.3333333333333px; line-height: 1.38; white-space: pre-wrap;"><br /></span></div> <div dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"> <span style="font-family: Arial; font-size: 13.3333333333333px; line-height: 1.38; white-space: pre-wrap;">Given that ambitious goal, Chrome has just milliseconds to produce every frame. But painting graphics to the screen isn't all that Chrome does, and there can be several different tasks contending for a single processor core. Historically Chrome handled execution of tasks, such as animating an image, responding to a click, or doing some memory operations, the same way that a bank handles a queue of customers: the first one line in is the first one handled. While this is simple and straightforward, it's not always the best for optimal performance. An urgent task, such as painting the next frame to the screen, might be added to the end of a long queue of pending tasks. The 60 frames per second goal would be lost.</span></div> <div dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt; text-align: center;"> <span style="background-color: transparent; color: black; font-family: Arial; font-size: 13.333333333333332px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;"><img alt="scheduler1.png" height="110px;" src="https://lh5.googleusercontent.com/IcUFdkPSmb93_7Fa6O1QkJbP5xbDkjeeuEHpO27Z0gVm_8C7iYc9QKEBf-TzQ7lYsitm0xAunHR5JjTe3h0SYWRgh6jV0y4vGMheDVHZFo05XYT6ufJvStmDWgxPd39z-qUuORI" style="-webkit-transform: rotate(0rad); border: none; transform: rotate(0rad);" width="515px;" /></span></div> <span style="font-family: Arial; font-size: 13.3333333333333px; line-height: 1.38; white-space: pre-wrap;">Starting in Chrome 41, we've created a task scheduler integrated into the Blink rendering engine. The scheduler is capable of evaluating pending tasks and reordering them so that the most urgent tasks, such as animating and responding to a user's action, are prioritized ahead of others. Lower priority tasks, such as clearing out unused memory, are delayed until the processor has available time. In practice, this results in up to a 40% higher responsiveness to user input when Chrome is working hard to draw frames.</span><br /> <div dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt; text-align: center;"> <span style="background-color: transparent; color: black; font-family: Arial; font-size: 13.333333333333332px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;"><img alt="scheduler2.png" height="110px;" src="https://lh4.googleusercontent.com/XqNys-mWtQzJRvPxzaMzXlvpdJxsax6-JkVFOwc5glY7ykz27LVQZDHF2SIZennPJSXe8Z6BYxHrd3D97pf-0EuH6IAozhkdUPn37QKwTvybBUp0rVL-_HKQD3s1NxG0-HXafVo" style="-webkit-transform: rotate(0rad); border: none; transform: rotate(0rad);" width="515px;" /></span></div> <span style="font-family: Arial; font-size: 13.3333333333333px; line-height: 1.38; white-space: pre-wrap;">However, even the most advanced scheduler can't properly queue up tasks without knowing what's coming in the future. To address this, the Blink scheduler is also integrated with Chrome's graphics engine, which has precise knowledge of when Chrome will need to deprioritize other tasks in order to paint graphics to the screen. This allows the scheduler to consider lower priority tasks and schedule only those tasks that fit nicely into the otherwise "idle" time before Chrome needs to draw another frame. These tasks are handled essentially for free, with no impact on the smooth, 60 frames-per-second animations.</span><br /> <div class="separator" style="clear: both; text-align: center;"> <br /></div> <div style="text-align: center;"> <iframe allowfullscreen="" class="YOUTUBE-iframe-video" data-thumbnail-src="https://i.ytimg.com/vi/07hy093cDjk/0.jpg" frameborder="0" height="266" src="https://www.youtube.com/embed/07hy093cDjk?feature=player_embedded" width="320"></iframe></div> <div dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt; text-align: center;"> <span style="background-color: transparent; color: black; font-family: Arial; font-size: 10.666666666666666px; font-style: italic; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">The latest version of Chrome scrolling a particularly challenging website, with the scheduler enabled (left) and disabled (right).</span></div> <div style="text-align: center;"> <b style="font-weight: normal;"><br /></b></div> <div dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"> <span style="background-color: transparent; color: black; font-family: Arial; font-size: 13.333333333333332px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">These changes demonstrate that performance isn't just about doing things faster - it's also about doing things smarter, in the right order, and at the right time.

Results so far are positive, with the data showing that QUIC provides a real performance improvement over TCP thanks to QUIC's lower-latency connection establishment, improved congestion control, and better loss recovery.</span></div> <b id="docs-internal-guid-901d6421-c84a-7dcf-813d-40e70630d041" style="font-weight: normal;"><br /></b> <br /> <div dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"> <span style="background-color: transparent; color: black; font-family: Arial; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">For latency-sensitive services like web search, the largest gains come from zero-round-trip connection establishment. The standard way to do secure web browsing involves communicating over TCP + TLS, which requires 2 to 3 round trips with a server to establish a secure connection before the browser can request the actual web page. QUIC is designed so that if a client has talked to a given server before, it can can start sending data without any round trips, which makes web pages load faster. The data shows that 75% percent of connections can take advantage of QUIC’s zero-round-trip feature. Even on a well-optimized site like Google Search, where connections are often pre-established, we still see a 3% improvement in mean page load time with QUIC. </span></div> <b style="font-weight: normal;"><br /></b> <div dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"> <span style="background-color: transparent; color: black; font-family: Arial; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;"><img height="336px;" src="https://lh3.googleusercontent.com/o62Ohn1Ppxna6zz0NtavqRyetjryOj-81Sz4bRt3U8lURVblk5RKOaCcf57i6BkmprremePJpq_sQcxfJiuA4wJBmRp3pR4BS1P-yiT6UNUPvnBeP_rLz9bvHxFE15kuNBM2hpE" style="-webkit-transform: rotate(0.00rad); border: none; transform: rotate(0.00rad);" width="624px;" /></span></div> <div dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"> <span style="background-color: transparent; color: black; font-family: Arial; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;"><br /></span></div> <div dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"> <span style="background-color: transparent; color: black; font-family: Arial; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Another substantial gain for QUIC is improved congestion control and loss recovery. Packet sequence numbers are never reused when retransmitting a packet. This avoids ambiguity about which packets have been received and avoids dreaded retransmission timeouts. As a result, QUIC outshines TCP under poor network conditions, shaving a full second off the Google Search page load time for the slowest 1% of connections.   These benefits are even more apparent for video services like YouTube. Users report 30% fewer rebuffers when watching videos over QUIC. This means less time spent staring at the spinner and more time watching videos. </span></div> <b style="font-weight: normal;"><br /></b> <br /> <div dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"> <span style="background-color: transparent; color: black; font-family: Arial; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Where do we go from here? Today, roughly half of all requests from Chrome to Google servers are served over QUIC and we’re continuing to ramp up QUIC traffic, eventually making it the default transport from Google clients — both Chrome and mobile apps — to Google servers. We plan to formally propose QUIC to the IETF as an Internet standard but we have some housekeeping to do first, like changing the wire format and updating our reference implementation from SPDY-over-QUIC to HTTP2-over-QUIC. In the coming months, we also plan to work on lowering handshake overhead to allow better server-side scalability, improving forward error correction and congestion control, and adding support for multipath connections.   </span></div> <b style="font-weight: normal;"><br /></b> <br /> <div dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"> <span style="background-color: transparent; color: black; font-family: Arial; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">If you want to follow along or play around, feel free to check out the </span><a href="https://chromium.googlesource.com/chromium/src/+/master/net/quic" style="text-decoration: none;"><span style="background-color: transparent; color: #1155cc; font-family: Arial; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: underline; vertical-align: baseline; white-space: pre-wrap;">code</span></a><span style="background-color: transparent; color: black; font-family: Arial; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;"> and </span><a href="https://www.chromium.org/quic/playing-with-quic" style="text-decoration: none;"><span style="background-color: transparent; color: #1155cc; font-family: Arial; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: underline; vertical-align: baseline; white-space: pre-wrap;">experiment</span></a><span style="background-color: transparent; color: black; font-family: Arial; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;"> with it, or join </span><a href="mailto:proto-quic@chromium.org" style="text-decoration: none;"><span style="background-color: transparent; color: #1155cc; font-family: Arial; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: underline; vertical-align: baseline; white-space: pre-wrap;">proto-quic@chromium.org</span></a><span style="background-color: transparent; color: black; font-family: Arial; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;"> as we continue to improve the Internet, one packet at a time.</span></div> <div dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"> <span style="font-family: Arial; font-size: 13px; white-space: pre-wrap;"><br /></span></div> <div dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"> <span style="font-family: Arial; font-size: 13px; white-space: pre-wrap;">Posted by SYN, SYN-ACK and ACK (also known as Alyssa Wilk, Ryan Hamilton and Ian Swett)</span></div> <span itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://plus.google.com/116899029375914044550' itemprop='url'/> </span> </script> <noscript> <div dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"> <a href="http://blog.chromium.org/2013/06/experimenting-with-quic.html" style="text-decoration: none;"><span style="background-color: transparent; color: #1155cc; font-family: Arial; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: underline; vertical-align: baseline; white-space: pre-wrap;">Last year we announced QUIC</span></a><span style="background-color: transparent; color: black; font-family: Arial; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">, a UDP-based transport protocol for the modern Internet.  Over the last quarter, we’ve been increasing the amount of traffic to Google services that is served over QUIC and analyzing QUIC performance at scale.

In the coming months, we also plan to work on lowering handshake overhead to allow better server-side scalability, improving forward error correction and congestion control, and adding support for multipath connections.   </span></div> <b style="font-weight: normal;"><br /></b> <br /> <div dir="ltr" style="line-height: 1.38;
