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

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

These are not the only compilers and interpreters. These are not the only programs that could be written. These are not the only tasks that could be solved. These are just 10 tiny examples.

 2 : Are the PHP programs faster? Approximately.

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

PHP used what fraction? used how many times more?
Time-used	|-	|---	25%	median	75%	---|	-|
(Elapsed secs)

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

 3 : Are the PHP programs faster? Measurements.

These are not the only tasks that could be solved. These are just 10 tiny examples. These are not the only compilers and interpreters. These are not the only programs that could be written.

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

 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.

 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.
