Hi bero,
done here: https://blog.openmandriva.org/2016/05/gcc-6-1-vs-llvm-clang-3-9-compiler-performance/
I did one test ( https://openbenchmarking.org/test/pts/hmmer-1.1.0 )
on 2014 and Lx3, both running the same kernel
(4.1.18-nrjQL-desktop-1omv) with 2 Gb ram and 2 processors inside
vbox.
Here is what I get. The times are the mean result of 5 successive tests.
2014
gcc: 24.34
clang: 25.53 s (clang 3.5 is a bit quicker)
Lx3
gcc: 26.86 s
clang: 27.55 s (clang 3.8 is a bit slower)
2014 is a bit quicker than Lx3 with this test.
