Zapcc Claims To Be A "Much Faster C++ Compiler"

Zapcc is the latest compiler I heard about this morning... Zapcc is based on LLVM's Clang C/C++ compiler but claims to be much faster than it.

Zapcc features "unique header compilation technology" to speed-up C++ compilations. On first-time compiles, results published by Zapcc show it compiling much faster than GCC and Clang. When carrying out subsequent compiles, the compile times are a fraction of the original time due to some header file caching, etc. They say, "zapcc is like precompiled headers on steroids."

On their website they don't readily have available any results showing the speed of binaries generated by Zapcc to see how much faster it is than Clang or GCC, but are reportedly looking at putting out some Phoronix Test Suite benchmark results on their site.

Zapcc is to be offered for Linux and Windows systems but at the moment the only access to this compiler is via a private beta program. It appears that Ceemple Software is looking to develop Zapcc into a viable commercial compiler. Soon as I have my hands on Zapcc I'll work on some of my own benchmark results compared to the notable open-source compilers on Linux.
