My box is thrashing badly with 30 users over telnet doing various things (cur specs:- 233/128M/20G ATA33 disk)! vmstat shows that memory really isn't a problem (it hardly touches swap) but it's in iowait 70% of the time (excuse the solaris term). It's being upped to a P2/400 with 256M RAM and a nice Asus board next week but is still stuck disk wise (I assume that is whats really causing the problems). Is it worth putting a 2-4 SCSI-UW disks in instead? If so, what is likely to be the best cost/performance economy:- 4 x 4.5Gb disk 2 x 9.1Gb disk Also, are those I-Will controllers any good? I don't really want to fish out for something like an Adaptec controller when an I-Will one will do the job probably just as well... Your suggestions and experiences are welcome. TIA - Chris.
