Hi John, every "recent" version I tried resulted in a slowdown so I didn't recompile very often; until tonight, I was still runninng a kernel from 20010214. Tonight I created a new kernel but I finally figured out I should take out most debugging options: options DDB # options WITNESS # options WITNESS_DDB # options MUTEX_DEBUG # options INVARIANT_SUPPORT # options INVARIANTS and now performance is very good, event with: kern.random.sys.harvest_ethernet: 1 kern.random.sys.harvest_point_to_point: 0 kern.random.sys.harvest_interrupt: 1 Later tonight (my locale) I saw a few other commits to ithreads and such, exp. your commit which should fix my issue with pccard (thanks a lot for that!), so later a will update again and start building kernels adding back the debugging options one at a time. I'll post the result. Bye, Andrea -- Actually, Microsoft is sort of a mixture between the Borg and the Ferengi.
