That was very interesting. Marceau technique seems to capture meaningful 
data in a visually attractive way. Thanks for the link!

It looks like the biggest Lua/LuaJIT performance outlier in the 2009 
test is fannkuch. The top performers take advantage of the multicore 
host system by creating threads to split up the work. It would be 
interesting to see if throwing luaproc at the problem would help. The 
test system is a quad core (mine at work and home are dual). A 
three-fold speed up would move Lua/LuaJIT up from rank 24 to 18 or so.

I've used neither luaproc nor LuaJIT for anything more than an initial 
evaluation, so it will be a fun little project while I'm away over the 
weekend. If I can get it working, I'll report back. Others should feel 
free to beat me to it.
