As far as we could tell (Mark I eyeball) the FreeBSD system finished faster. We even disabled the be_nice setting on the FreeBSD laptop and it still stayed fairly responsive, a little sluggishness but nothing like on my system. Another thing when we do a count of the number of nessusd processes running, mine are significantly less. I'm guessing these has to do with how Linux and BSD handles threads and wondering if there may be some tuning options that could be done on Linux for this. Mind you these are all eyeball measurements, no formal numbers though. _______________________________________________ Nessus mailing list [email protected] http://mail.nessus.org/mailman/listinfo/nessus
