Erlang HiPE speed ÷ Java 7 speed | Computer Language Benchmarks Game

1 : Are the Erlang HiPE programs faster? At a glance.

Each chart bar shows, for one unidentified benchmark, how much the fastest Erlang HiPE program used compared to the fastest Java 7 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 Erlang HiPE programs faster? Approximately.

Each table row shows, for one named benchmark, how much the fastest Erlang HiPE program used compared to the fastest Java 7 program.

Erlang HiPE used what fraction? used how many times more?

3 : Are the Erlang HiPE 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 Erlang HiPE program are shown for comparison against measurements of the fastest Java 7 program.

4 : Are there other Erlang HiPE programs for these benchmarks?

Remember - those are just the fastest Erlang HiPE and Java 7 programs measured on this OS/machine. Check if there are other implementations of these benchmark programs for Erlang HiPE.

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

5 : Are there other faster programs for these benchmarks?

Remember - those are just the fastest Erlang HiPE and Java 7 programs measured on this OS/machine. Check if there are faster implementations of these benchmark programs for other programming languages.
