Phoronix: Some Compiler Performance Benchmarks With The Zapcc Caching Compiler

Here are some quick benchmarks I ran this week of the newly open-sourced Zapcc C++ caching compiler based upon LLVM/Clang and compared to the upstream Clang performance, GCC, and Ccache with the speed on the original compilation of the benchmark code and then again on a subsequent compilation...

What per-server-process RAM limit is that with?

thanks for testing, as expected zapcc delivers very good compile times

These results show that zapcc is not that good compared to ccache or I am missing something?

I'm not sure what you're looking at but only the last test shows ccache being faster than zapcc and it is understandable as libvpx is a C library with a lot of hand written ASM and zapcc main focus is to accelerate C++ templated code. Notice that zapcc is faster in the first run in many cases from other compilers.. that is more important than anything else.

I would be very interesting to benchmark large projects that make heavy use of C++ templating, such as Chromium or PCL.

Boost math should be a good example of it and Zapcc advertises big advantages.

Zapcc could make Gentoo fly again
