Does it matter? 90% of the "shell" systems I see have poor performance because they are out of memory and swapping like a dog. Another 9.99% have enough memory, but because there aren't enough disks / fast enough disks everything is blocked waiting on io. Only 0.01% of them have I ever seen be CPU bound (100 tintin++'s can do that to you :-). Unless it's a compiler farm, or you have lots of users running specialized apps (mathematica, staroffice) I bet pouring your money into memory and io bandwidth will make the system more 'responsive' to the end users. -- Leo Bicknell - bicknell@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ Read TMBG List - tmbg-list-request@tmbg.org, www.tmbg.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
