Waterfox | The fastest 64-Bit variant of Firefox!
Waterfox is a 64-Bit version of Firefox. The Firefox source code is taken and compiled to run specifically for 64-Bit Windows computers. To make Waterfox stand out a bit more, it’s compiled with optimizations so that it will run more efficiently and faster than just compiling Firefox as a 64-Bit program. For some people with older systems, the 64-Bit version loads quicker and is much more responsive than the 32-Bit build.
How does it compare to 32-Bit Firefox?
In benchmarks, the 64-Bit variant of Firefox out-performs the 32-Bit variant. Also because this variant is being built specifically for Windows, there might be further performance increases.
Were there any optimisations made?
Yes, Waterfox was compiled with SSE, SSE2, x64 favoring and the following optimization flags: /Og /Oi /Ot /Oy /Ob2 /Gs /GF /Gy
What's new in Waterfox version 28.0:
- A complete, 100% ICC build! Yay! (As opposed to various VC and ICC build).
- Profile-Guided optimisation is back, which brings nice performance improvements.
- If you're running an Intel CPU, support for AVX2, SSE4.2, SSE4.1 and SSSE3 if your processor supports these instruction sets. AMD users, at the moment you only get up to SSE3 support
- Using Mozilla's built in memory allocator as opposed to jemalloc, otherwise crashes occur.
