Step 4 : Are there other Erlang HiPE programs for these benchmarks?
Remember - those are just the fastest Erlang HiPE and Java 6 -server 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.
Step 5 : Are there other faster programs for these benchmarks?
Remember - those are just the fastest Erlang HiPE and Java 6 -server programs measured on this OS/machine. Check if there are faster implementations of these benchmark programs for other programming languages.
Maybe one of those other programs is fastest on a different OS/machine.
