User-Agent:       Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; WOW64; SLCC1; .NET CLR 2.0.50727; .NET CLR 3.0.04506; Media Center PC 5.0; InfoPath.2)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.8.1.10) Gecko/20071115 Firefox/2.0.0.10

I am running 15/15 FIOS.  When I run speedtests in Firefox I get ~14.7/2.3.  It is always 2.3 upload.  In IE I get ~14.7/~13.8.  The upload file is too small to let it get up to full bandwidth.

Reproducible: Always

Steps to Reproduce:
1.Try running a speedtest from speakeasy.et or speedtest.net in Firefox and IE on a machine with over 2.3 Mbps upload.
2.
3.
Actual Results:  
You only get 2.3Mbps upload through anything in Firefox.

Expected Results:  
Give somewhere around 14Mbps upload

It would be interesting to know if this still happens with nightly Firefox 3 builds...

Anyone else with high upload able to confirm on another network?  I was wonderring about FF3 as well.

I tried Firefox 3 Beta and it was better but seems to limited to around 5Mbps.  Here is a side by side of FF3b1 and IE7.  http://www.ferruminfusco.com/Speedtest%20FF3%20IE7.jpg

How are you doing this upload, exactly?  What protocol is it using?

Comment 8

[Mark Christensen]

It is just HTTP bandwidth test from speedtest.net.  It doesn't matter whos spoeed test I use though.  They all turn out low in Firefox and fine in IE.
