Performance Tuning PHP

The first step to tuning PHP begins with compiling an optimized version of PHP.

• Enable all compiler optimizations with -O3

• Make the compiler tune the code to your CPU via -march -mcpu Use Caution

• Try to make the compiler use CPU specific features -msse -mmmx -mfpmath=sse

Revised Build Procedure



export CFLAGS="-O3 -msse -mmmx -march=pentium3 -mcpu=pentium3 -funroll-loops -mfpmath=sse"
./configure
make
make install
