High Performance Networking in Google Chrome

I've noticed that Google Chrome gives me noticeably slower speeds than Firefox, et al.

From high ping. (+100 ms) To slower download speeds. (8+/- Mbit/s of the advertised 30 Mbit/s) To slower upload speeds. (2-3+/- Mbit/s of the advertised 5 Mbit/s) (Oceanic Time Warner Road Runner)

I used to really like Chrome, but after noticing the speed discrepancies I've ceased using it.

I'm not sure if it's due to Google Chrome's FreeBSD implementation vs Windows, but I get similar speeds using Google Chrome, and Chromium, on other Unix-like systems as well. (Not a Windows user, so I've not tested Chrome/Chromium on Windows.)

I used to have the same gripe with Firefox for a good couple years. Turned out my profile had.. something.. in it that was slowing down nearly every activity. I'd strongly suggest nuking your Chrome profile and any other lurking config or cache if you can. In my experience, old browser profiles seem to sometimes hide slow juice as it were, haha.

As mentioned above, I've never created a Chrome/Chromium user profile. I had the browser setup to clear cache and cookies on exit, and I'm aware of extensions/add ons slowing things down so I tested with a fresh install - no add ons/extensions - and a fresh OS.

I'm not trying to dis Chrome/Chromium as I really like the UI.

I've tried http://speedtest.net/ and when I complained to my ISP they sent me to their own site, http://speedtest.oceanic.

Interestingly, this morning's tests totally discredited my previous accusations regarding Chrome/Chromium. (The net Gods must have intervened)

Chromium on Xubuntu 13.04 ===> http://www.speedtest.net/my-result/2940424253

Chromium on Xubuntu 13.04 ===> https://paste.xinu.at/EWUab/

Firefox on Xubuntu 13.04 ===> https://paste.xinu.at/8ky/

Never mind... Disregard my complaints. It seems like Chromium is on par with Firefox this morning.

I think there is something else going on here. While it's plausible that different browsers may introduce some processing latency, we are definitely not talking about 100ms+ delays, or 30 to 8Mbit throughput drop. More likely.. try disabling your extensions, see if that helps. If that doesn't help, try creating a new profile.

I've conducted my tests with zero extensions/add ons, and I've never made a user profile.

OT: Anyone used QUIC protocol in production for non-Chrome purposes?

AFAIK, no.. Maybe in private. If you're interested, checkout the Chromium source, there is a basic demo server checked in. Perhaps more importantly, we don't encourage people to at this point because it's a fast moving target with high code churn... unless you're willing to keep up. :)
