Interesting FF26.0 speed results
« on: December 23, 2013, 12:02:19 PM »

Wondering if anyone else sees similar.

Firefox 26.0 :



IE11 :



Would normally have put this into another section but its only apparent on speeds above 40Mbps.

All add-ons disabled/reset. Antivirus disabled.

Flash plugin differences is all I can think of.

Anyone else want to suggest why FF26.0 sucks at multiple http connections?

The maximum number of connections is one of the hidden options that you can change through about:config, and there's also a Firefox addon which can set different levels. It's generally considered to be a bit antisocial to set the value too high, because websites have limits on the total number of connections they can support, and they don't want a comparatively small number of clients saturating their capacity. There was a bit of a fuss about this a few years ago, and I think that since then, FF has maintained a lowish default value.

The limit in FF26.0 is 6 persistent connections to the same server so its presumably being limited by something within FF26.0/plugin-container.exe/FlashPlayerPlugin_119_900_170.exe?

Will bump limit to 7 and see.

Edit - nope its not that, TBB test has been chosen so it works with FF and limits connections to 6. Not particularly bothered, just curious really.

the firefox default is now way higher than 6 I am pretty sure of it.

The social responsiblities thing seems completely out the window now, most major sites deliberatly use many subdomains to encourage browsers to use more connections.  Plus firefox for a while has had higher defaults.

The only thing I can think off is somehow firefox is restricting your tcp recieve buffer.

I've never changed mine and I just checked and it is indeed set to 6 in about:config so I believe the default is still 6.

ok yeah it is indeed 6, although the RFC guidelines state 2 so the browser is breaching.

Incidently mine is set to 4 and I have no issues on that test.
