Someone could help us? We have a dual Pentium III 500MHZ with 256MB RAM and 2x18GB SCSI disks tied with vinum. This machine runs postfix-19991231 with radius authentication for about 40.000 mailboxes over FreeBSD 3.4. The top command reports 90% of the time the CPU is above 95% idle (see below). Despite this, it takes about 10 seconds to show the first screen of a vi command. Another strange symptom is the report from iostat (see below). It shows a great discrepancy among our disks, mainly in the msps measure. It also shows a great discrepancy (very high numbers) about what should be the msps of any SCSI disk. This configuration is running for months and we have no report of hardware or software failure or malfunction whatsoever. Could the numbers from iostat be wrong? Could the numbers from top be wrong? What else could be wrong? What can we do? Thanks. ------------- Elias A.
