Baptiste Wicht achieved significant gains using Zapcc over GCC and Clang on his Expression Template Library (ETL):

“The result is pretty clear! zapcc is around three times faster than Clang and around two times faster than GCC. This is pretty impressive!”

David Carlier checked Zapcc and reported roughly 2X compilation speedups for LMMS, the popular professional music production platform and for OpenCV, the extremely popular computer vision library:

“Better, stronger, faster … there is zapcc”

The chair of Applied Mathematics and Numerics at the Department of Mathematics of the TU Dortmund, is developing a C++ Version of the FEAT (Finite Element Analysis Toolbox) package, designed to solve large scale Finite Element based problems in a highly efficient way across a wide variety of modern hardware architectures. FEAT is devised with efficiency, encapsulation and multi-architecture support in mind.

“Using Zapcc, we were able to reduce build times to 1m47s, vs clang 3.8 3m00s, almost a 2X build speedup on a Xeon E5-2670 system.”

“First of all, damn this compiler is fast ! I’ve challenged someone at school who still uses default g++, and wouah, I beat him from far. All that to say that zapcc is an amazing compiler, your team made awesome job ☺ !”

C++ compiler guns for speed records

Developers dread the delays for a C++ project to build, but Zapcc, a variation on the Clang/LLVM compiler, cuts wait times by half or more

“Israeli software outfit Ceemple Software Ltd. recently concluded a round of beta testing for what it hopes to be a major fix for that problem: Zapcc, a compiler that can cut compilation times for many C++ projects by half or more.”
