In the last week, Chrome (latest version, 24.0.1312.57) on Windows 7 (64 bit) has severely deteriorated in download speeds and latency. Using speedtest.net, Chrome is currently receiving ~2.5mbps down and ~600ms ping times, while Firefox, Safari, IE, and Opera consistently have ~40ms pings and ~12mbps download speeds.

So in an attempt to correct this issue, I've taken these steps:

  • I first cleared the entire cache (no effect)
  • I then disabled every extension (no effect)
  • I uninstalled and reinstalled Chrome (no effect)
  • Ran a virus scanner (avast), no threats found

What's strange is that Chrome works fine if it's using an incognito tab. If anyone can help, that'd be great, because I do enjoy using Chrome over Firefox.

Could it be due to one of your Chrome extensions? As most of those are disabled in incognito tabs. –  Dan D. Feb 18 '13 at 3:37
As noted, I did try this, though it had no effect :( –  Wes Cossick Feb 18 '13 at 3:39
Can you try chrome.exe --enable-npn-http or chrome.exe --enable-npn-http --use-spdy=off and see if that changes anything? –  Karan Feb 18 '13 at 5:00
Unfortunately, neither had any effect. –  Wes Cossick Feb 18 '13 at 5:21
I'm having very high DPC latency suddenly in Chrome as well. When I resize the window my audio stutters! –  Damon Jun 8 '13 at 3:46
