Here are the builds.  (these are experimental builds).

To change the values, edit all.js:

pref("network.default.buffer.size", 16384);
pref("network.default.buffer.count",32);

The defaults in Firefox are 4096 and 16 respectfully. You probably can change these values via about:config (and the patch doesn’t prevent you), but that may be bad.
