Speed test results.

[fink]

I've recently signed up with a new hi speed fibre internet company. I'm getting 1G (ish) measured up and down on various reliable speed test sites on all of my Chrome based browsers... Brave, Vivaldi and Chrome original so no actual problem there. But when I run the tests on the latest Firefox It regularly tops out at less than 350Mbps. Even disabling all addons and also running it in troubleshoot mode it's still showing slower speeds. It's networking settings are all blank as well.. no VPN etc.

Not a show stopper since even 300Mbps is more than fine for browsing, movies etc I just find it odd that it seems to be slower. Interestingly it renders pages a bit faster than either Brave or Vivaldi so that's why I tend to use it more often.

Ideas?

What version of Firefox are you running?

Did you try the portable version? That would have a clean profile.

The latest. 106.0 But this was also happening on the previous/recent 1.5.x versions before I updated it.

I'll try the portable ver later tonight when I've got some time.

Made some time now LOL

Same slower results with the portable version running in its own folder totally isolated from all other programs on the computer.

You can also look at Performance settings. Hardware acceleration should be enabled by default. Not sure how those would affect Speedtest, but it's worth a look.

Ah, just saw your post about portable FF. Hmm.

This is a bit old, so I'm not sure if it will help.

Set browser.tabs.remote.autostart = false in about:config. Default is true.

Hardware acceleration is enabled (on all browsers)

Tried Set browser.tabs.remote.autostart = false in about:config. Default is true.

Didn't make a difference.

Another thing I just had a look at is CPU use.. Firefox uses around 85% on the tests on average and Vivaldi uses close to 95%. Don't thing that's a reason for any speed discrepancies just an observation.

[Midknyte]

Ah well. I haven't found any obvious fixes. I usually stick to the ESR versions. You'd expect the performance on the Release versions to be better.

I'm not lucky enough to have Gig speeds at home, so I can't really compare them myself.

[Midknyte]

Did you try any other speed testing sites?

Yeah I've used a half dozen different sites.. all reliable ones I've used for years.

Just ran a quick comparison at work. Firefox 102.4 ESR vs Google Chrome 106.

The results were pretty close. Both were done from portable version with clean profiles. I do notice that there are a ton of ads on speedtest.net when I don't have an ad blocker on. Not sure if that has anything to do with it.

Firefox 102.4 ESR
907.88 down
871.94 up

Chrome 106
920.09 down
870.42 up

Interesting. I'm baffled. I use fast dot com most of the time and there are no ads there at all from what I can see.

Hmm. Maybe it could be a CPU or antivirus issue? FF has had issues with AMD CPUs and Avast AV recently.

Bypassed Avast a/v and no difference and it's an older gen Core i5 so that shouldn't be an issue.
