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

Each chart bar shows, for one unidentified benchmark, how much the fastest Go program used compared to the fastest PHP 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 Go programs faster? Approximately.

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

Go used what fraction? used how many times more?

 3 : Are the Go 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 Go program are shown for comparison against measurements of the fastest PHP program.

 4 : Are there other Go programs for these benchmarks?

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

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

 5 : Are there other faster programs for these benchmarks?

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