I was reading how older versions of Firefox could be sped up by using "network.http.pipelining”. There were a host of additions that were to be added to about config, but, that was before version 29.
So, I looked up "network.http.pipelining” in the about:config of 29 and saw that it was disabled (set to false). So I set it to true and saw a noticeable speed boost loading pages. In the older versions, setting maxrequests over 8 was redundant, but, in version 29, maxrequests was preset for 32.
I wonder why the default was set to false? I'm also wondering if I should set "network.http.pipelining-ssl also to true. I'm still looking, but, I thought I'd post to see if anyone else has used pipelining to speed up Iceweasel. Anyone?
