I saw this recently. I'm fed up with Tor's molasses in winter speed and was wondering if anyone has tried this or knows about it: Hacking Firefox for Maximum Performance with Tor Introduction Tor is known for being secure but slow. If you want to improve browsing speed a bit, please follow the following simple instructions for tweaking the Firefox web browser's settings: Procedure 1 First, open Firefox's advanced settings menu by running about:config from the address bar. Upon entering this address, you will see a long list of internal settings. Modify the following ones and set them to the suggested values shown here for maximum performance: network.http.keep-alive.timeout:600 (300ms default is OK usually, but 600 is better.) network.http.max-persistent-connections-per-proxy:16 (Default is 4) network.http.pipelining:true (Default- false. Some old HTTP/1.0 servers can't handle it.) network.http.pipelining.maxrequests:8 (No default) network.http.proxy.keep-alive:true (Default- true, but double check) network.http.proxy.pipelining:true (Default- false) Afterwards, just restart the browser and experience the difference! For some automated additional performance hacks, check out FireTune. Currently, FireTune is only for Win32, but you can do the same tweaks manually with the help of this page. Additionally, there is the FasterFox extension that is easy to install, and is also platform independent!
