Sorry this isn't in your standard template format which is ideal for single issues, this appears to be more of a general problem, hence the prose.
I'm a web developer who's been using Chrome as my default browser almost since it came out, many years ago. Over the last 6 months or more I've noticed it getting less performant with each update. It's slower to do stuff like respond to mouse events, animation, dreadfully slow at site first accesses and really awful playing embedded video such as YouTube and Vimeo movies. Running Chrome seems to cause everything else to slow up as it take so much memory and CPU resource. Video runs better if I switch out hardware acceleration in settings, but then I get huge chunks of missing web page when I mouse over stuff, which is totally unacceptable.
My machine is a pretty powerful Dell M3800 i7 laptop with 16MB RAM running Linux Mint 18.1 x64 with cinnamon desktop and the 4.10.x kernel. Although the machine has an nVidia GPU I use the integrated Intel GPU as the nVidia drivers aren't up to the job yet.
Switching to the latest FireFox browser, all the above issues disappear, so I've set it as the default browser. I'll just have to get up to speed on it's dev tools which I rely on a lot for work.

Do you see the slowness specifically on mouse events, animation, site first accesses etc. that you named, or you feel slowness in general? If you pinpoint what seems going wrong, it would be very helpful. If you see any anomaly in Chrome's task manager (e.g. some tab eating 100% of CPU, or consuming lots of memory etc.), then it is also helpful to continue investigation. For further investigation on performance issue, Chrome provides some tools (developer tools, or chrome://tracing ) to look into the performance in greater details. Also, trying the same without any extensions, incognito mode, or fresh profile (delete all your profile in ~/.config/google-chrome) (or all of them) fixes the problem, maybe something went wrong with your locally-stored profile data. Usually this kind of problem is hard to track down, but worth trying to see what makes difference. Any feedback is welcome!

Craig - could you respond to comments #2 or 3?

Following further general degradation I managed to ascertain that the machine's CPU's were overheating and Linux was backing-off the load. A thorough clean of the CPUs' heatsinks and general dust removal from fans and filters has resulted in a much quicker machine. Consequently, I'm at a loss to find an issue following the chrome ffmpeg update I noticed a few days ago. Even YouTube is behaving itself. It's a Dell Precision M3800 which is left permanently switched on with the lid shut. Chrome is back as my default browser :)

Great to hear your Chrome's performance is back to normal again! It sounds your issue is now resolved, so closing this. If you have any further findings, feel free to reopen if it is really a bug in Chrome software, or file a new bug. |
