Zapcc Is Showing Compile Times Even Faster Than LLVM Clang

The Zapcc compiler stack is proving to be faster than LLVM/Clang at compiling C++ codes, which in turn is much faster already than GCC. The performance of the generated binaries from this LLVM-based compiler stack is on-par with what's offered by Clang.

Back in May is when we first heard of Zapcc when they claimed to be a much faster C++ compiler. Since then, they've still been hard at work on this LLVM-based compiler being produced by Ceemple Software in Israel. They've invited me to benchmark Zapcc for comparison purposes and it's still on my never-ending TODO list, but today they shared they've uploaded some of their own benchmarks compared to Clang.

Over at zapcc.com/benchmarks are their own in-house benchmarks comparing Zapcc to Clang. Of course, they were using the Phoronix Test Suite for benchmarking. They also developed a number of new test profiles that I'll work to get upstreamed and available on OpenBenchmarking.org shortly.

Ceemple's benchmark results show Zapcc to be significantly faster than LLVM Clang at compiling. In terms of the runtime performance, it's basically right on par with Clang.
