Thanks.
I should probably have mentioned that I'm basing my statement on a series of experiments on HT performance I ran a while ago when I was involved with debugging and tuning a
fairly large cluster.
The result showed that the performance gain from running two processes on one HT cpu varied a lot with the software run, with everything from <5% to >50% depending on how well the software was optimised for the cpu.
The better the software was optimised, the less the gain from running two copies.
15% gain sounds like it's quite optimised to begin with.
