I made a non-scientific benchmark on my laptop with my project. Although
jumping from -O2 to -Ofast giving me dramatic speed boost, it's interesting
to see that going from gcc-4.9 to clang-3.9, there's no difference, just
margin of error. The test is non-scientific, I worked on my PC at midday on
r
Thank You!

Seems like --with-cc=clang flag is where I can define clang compiler. Is it
safe to use with --with-cc-opt='-std=c11 ...? I think clang uses C11 anyway.

The default --with-cc-opt flags for Nginx are these:
*--with-cc-opt='-g -O2 -fstack-protector-strong -Wformat

However I added more optimizations, which are against the standard:
*--with-cc-opt='-g -Ofast -march=native -ffast-math
