after hearing of the big gains running universe on linux with the new glib (general libraries?) i downloaded a new Mint iso and fired up a vm. the gains were definitely noticeable over win7. I wasn't able to get both cpus running under a single vm so under advice i went native, didnt install just running live usb for now, the times are even faster.. 25-30% when i ran 12 WUs on 2x x5650s (12c/24t). after i ran 12 through at around 55mins each i went to 18threads, and my times were almost double. i dropped to 16, then 14 of the 12 physical. i was getting 90 mins per wu at 14threads, so i went back to 12 and it seems to be better credit overall.

anyone else able to share their experience with/without HT on native linux?
