I have a set of Macros, A Kit for K-meleon.

I found some secret settings that does speed things up a bit.
"app.update.enabled",false);
"content.notify.ontimer",true);
"content.notify.interval",240000);
"content.notify.backoffcount",10);
"network.http.pipelining",true);
"network.http.pipelining.maxrequests",8);
"network.http.proxy.pipelining",true);
"network.http.pipelining.firstrequest",true);
"network.dns.disableIPv6",true);
"nglayout.initialpaint.delay",0);
"network.http.max-connections",48);
"network.http.max-connections-per-server",24);
"network.http.max-persistent-connections-per-proxy",16);
"network.http.max-persistent-connections-per-server",8);
"browser.cache.disk.capacity",76800);
"browser.cache.memory.capacity",65536);
"javascript.options.jit.content",true);
"javascript.options.jit.chrome",true);
"content.interrupt.parsing",true);
"content.max.tokenizing.time",2333333);
"content.switch.threshold",849999);
These settings work with 1.5+ and 1.6a4+
But you might have to put the speed settings your self in
about:config to pave the road so the macro will work.
All other macros are working, it is just the speed settings you
might have to put in there.
If anyone knows of any more settings in about:config let me know!
