Not sure what you mean by "performance" in the subject. We're not building anything with clang yet, apart from clang itself. We have simply added clang. The rest of the build is identical. And yes, clang is a big C++ program and C++ code compiles s l o w l y. > Is this a normal behavior? The exact numbers are a bit odd, but generally speaking, yes, adding clang has substantially increased the build time. I see about a doubling on Xeon E3-12xx-based machines for make -j4 build. -- Christian "naddy" Weisgerber na...@mips.inka.de
