Perform a clean installation of each one and use each of them for a week. Let us know how you get on in the forums. Benchmarks are good if you like numbers, but real-world tests and subjective feelings are better for this, imo. My gut instinct tells me there really isn't a lot, if anything, between them.

Eins.MY said,
so between palemoon, waterfox and stock firefox 18, which one is faster? need benchmark results

I've used Waterfox in the past and still have Firefox 18 installed on the side. But my personal preference goes out to Palemoon.
Palemoon makes Firefox feel as fast and lightweight as IE, ironware or opera.

Just did a few quick checks inbetween.
Palemoon is about a second faster with starting up.
Going to results in FF taking 6% CPU and palemoon around 2.
Memory with just 1 tab open, is 109.3MB on palemoon and 64.5MB for Firefox.
Palemoon has a few plugins, stylish, reloadevery, imacros and firebug. Where Firefox is a clean install.
Havent used Waterfox in ages, so not sure how it matches up nowadays.

Although it was a .1 incremental release. Palemoon 15.4 has been incredible. It's lightweight and very very fast JavaScript-wise.
