1 : Are the Perl programs faster? At a glance.
Each chart bar shows, for one unidentified benchmark, how much the fastest Perl program used compared to the fastest Lua 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 Perl programs faster? Approximately.
Each table row shows, for one named benchmark, how much the fastest Perl program used compared to the fastest Lua program.

3 : Are the Perl 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 Perl program are shown for comparison against measurements of the fastest Lua program.

4 : Are there other Perl programs for these benchmarks?
Remember - those are just the fastest Perl and Lua programs measured on this OS/machine. Check if there are other implementations of these benchmark programs for Perl.
Maybe one of those other Perl programs is fastest on a different OS/machine.
