I've done a bit of checking and came to the conclusion that IO was NOT an issue, as both disks loads are very even and in the low teens to low 20%-ile of use. I changed the uniVerse tunable FSEMNUM from 23 to 53. Today, so far, the load average is in the low 2s instead of in the 3s and 4s. Of course we only have 30 of 42 users, so time will tell... The symptoms of the performance problem is that users notice things going very slowly, especially selects and sorts, but also when typing text there are pauses of parts of a second to a couple seconds when the system is very sluggish. -- Karl L.
