WaterFox - The 64 Bit Optimized Build Of Firefox

While there is no x64 Bit build of "Google Chrome", in my quest to look for a performance oriented 64bit native web-browser I found variations of "Mozilla Firefox" specifically optimized and compiled for 64 Bit Windows OS. Both WaterFox and PaleMoon forks features an x64 optimized firefox version for download, but since WaterFox optimizations are "only targeted" towards 64bit systems I tested Firefox x86 (32 Bit) Vs WaterFox x64 and the results are as follows.

Firefox 32 Bit Vs WaterFox 64 Bit

The WaterFox builds are compiled with only one target in-mind - a high performance speedier browser based on the Mozilla Firefox source code compiled specifically for 64-Bit systems. While compiling the SSE, SSE2, x64 and /Og /Oi /Ot /Oy /Ob2 /Gs /GF /Gy optimization flags are used for best optimized build.

Interestingly and contradictory to many other benchmarks and expected results, the Firefox x86 vs WaterFox x64 resulted in "Firefox 32 bit" scoring high amongst the two on my Windows 7 64 Bit machine using Peacekeeper browser benchmark.

I don't wonder that Firefox 9.0.1 x86 has more points,here I firstly saw WaterFox, I think in some time it can increase its parameters, though fps on renderGrid01 is rather high. In general I just can tell that I don't like so fast changing of new versions, I can't choose it for using because every month new one is coming.

Yeah, I noticed that also. maybe the overall results difference was due to the fact that 32 bit version was using a newer version featuring more optimizations and features.

emm, I also think so, and 32 bit version is still so popular.

It ALL depends on your hardware.

eg... i7-2600K

IMAGE score of 15905 (chrome)

I tested both builds on a Core i5, 4GB DDR3 system running Windows 7 SP1 64 Bit under same conditions.

That's strange , i think somethings up.
It seems like a very low score relative to what I get and others get.
Your score should be higher than that.

test a chromium browser to see if it's similar.
also try turning off Gpu acceleration in FF. (might be an issue)

I've been using both since November 2010 (Waterfox has been around quite a while) on Windows 7 x64 Pro, AMD Phenom II x6 1075Thuban (Vision Black) platform, with no noticeable difference for average, everyday surfing -- maybe, unless there's a race -- except KeyScrambler Personal can't work with 64-bit Waterfox. Neither does Trusteer Rapport. Frankly, I was looking for a significant edge whichever side has (=


Thank you for your test. I had a feeling there was not that much difference after trying out Waterfox on my Sandy Bridge i5 at 3·3 GHz. If anything, it turned out to be buggy, with the program staying in the processes for ages after the window was closed. I occasionally test the 64-bit Nightlies and they seem quicker than Waterfox.
