Google Outlines Performance Enhancements Coming to Chrome for Mac

Posted by · 7183 views · Translate
While Google Chrome is a great browser, many have criticized it for being a resource hog -- sucking up processing power, memory, and battery life. These issues are especially true on Mac OS X when compared to Safari.

Today, Google's software engineer Peter Kasting, has announced that his team is working on several under-the-hood enhancements that should address some of the performance issues Mac users are experiencing. For instance, one change made includes tweaks to the way tabs are rendered in the background. Below is an outline of all the fixes that should make their way to Chrome users soon:

Before: Renderers for background tabs had the same priority as for foreground tabs.
Now: Renderers for background tabs get a lower priority, reducing idle wakeups on various perf test, in some cases by significant amounts (e.g. 50% on one test).

Before: On a Google search results page, using Safari's user agent to get the same content that Safari would, Chrome incurs ~390 wakes over 30s and 0.3% CPU usage vs. Safari’s 120 wakes over 30s and 0.1% CPU usage.
Now: 66% reduction in both timer firings and CPU use. Chrome is now incurring ~120 wakes over 30s and 0.1% CPU use, on par with Safari.

Before: On capitalone.com, Chromium incurs ~1010 wakeups over 30s vs. Safari's ~490 wakes.
Now: ~30% reduction in timer firings. Chrome is now incurring ~721 wakeups over 30s.

Before: On amazon.com, Chromium incurs 768 wakups over 30s and consumes ~0.7% CPU vs. Safari's 312 wakes over 30s and ~0.1% CPU.
Now: ~59% reduction in timer firings and ~70% reduction in CPU use. Chrome is now incurring ~316 wakeups over 30s, and 0.2% CPU use, on par with Safari at 312 wakes, and 0.1% CPU use.


Kasting also noted that the Chrome Team will "continually improve" in this area.

Use App Tamer if you're running Chrome.

Still not worth it to me as it is still hogging battery life on my MacBook.

I did switch from Chrome to Safari for this very reason. I still use Chrome occasionally but will use it more after these fixes. Both are great browsers though.
