 Step 1 : Are the PHP programs faster? At a glance.

This chart shows 3 comparisons - Time-used, Memory-used and Code-used ~ speed and size.

Each chart bar shows, for one unidentified benchmark, how much the fastest PHP program used compared to the fastest program.

 Step 2 : Are the PHP programs faster? Approximately.

This table shows 3 comparisons - Time-used, Memory-used and Code-used ~ speed and size.

Each table row shows, for one named benchmark, how much the fastest PHP program used compared to the fastest program.

PHP used what fraction? used how many times more?
Benchmark	Time	Memory	Code

± read the measurements and then read the program source code.

 Step 3 : Are the PHP programs faster? Measurements.

This table shows 5 measurements - CPU Time, Elapsed Time, Memory, Code and ≈ CPU Load ~ speed and size.

For each named benchmark, measurements of the fastest PHP program are shown for comparison against measurements of the fastest program.

 Step 4 : Are there other PHP programs for these benchmarks?

Remember - those are just the fastest PHP and programs measured on this OS/machine. Check if there are other implementations of these benchmark programs for PHP.

Maybe one of those other PHP programs is fastest on a different OS/machine.

 Step 5 : Are there other faster programs for these benchmarks?

Remember - those are just the fastest PHP and programs measured on this OS/machine. Check if there are faster implementations of these benchmark programs for other programming languages.

 PHP : scripts embedded in html and much more 

PHP 5.2.10-2ubuntu6.4 with Suhosin-Patch 0.9.7 (cli) (built: Jan 6 2010 22:41:56)

Overall Performance: PHP is rarely the bottleneck (HTML slides)
