Here be the compile time flags.

export CFLAGS=”-O3 -march=cpu -pipe -msse2 -m3dnow -fomit-frame-pointer -mtune=cpu” CXX=gcc CXXFLAGS=”-O3 -cpu -felide-constructors -fno-exceptions -fno-rtti”

As mentioned in my previous entry you can go check the GCC Manual pages to replace the cpu keyword in the mtune and march in the CFLAGS and the -cpu in the CXXFLAGS.

I got approximately a 5% performance boost with these during benchmarking.

Please note though that the developer team got a much bigger increase in performance when they optimized the tables by adding indexes and improving their queries.

In general we also found that a simple select query took about twice as much time when the table was using InnoDB compared to MyISAM.

I am open to any additional feedback and ideas anyone may have.

The following settings worked really well for me

1 – export CFLAGS=”-march=cpu -O3 -pipe -msse2 -m3dnow -fomit-frame-pointer -mtune=cpu”

Based on whatever processor architecture you were using you should then replace the cpu in the above line with the name of the processor as described in GCC Manual

2 – Try configuring with the following flags added: –enable-inline-optimization

3 – Once compiled use strip to reduce the PHP binary size like so -> strip php-cgi

4 – For a significant performance boost I would recommend the installation of an opcode cache such as x-cache. If you don’t know what an opcode cacher is or does go here

The above mentioned optimizations led to more than 50% increase in speed and a more than 50% drop in cpu usage. Please feel free to make additional suggestions on how I can squeeze more performance  out !
