Some remarks :
- the aligned version of memory access whenever possible should be use: it surely helps

more than 10% improvements...

You should really look at the generated SSE code.
Can you paste the result of each test on this list?
At the moment i am testing with the whole jmax, i'll try to write small test
programs, and i'll post programs, results and assembler.
Well, in the next few days ...
