Hello all,
I've got a P-650 running AIX 5.2, in dlpar mode.
The 650 has 8 partitions on it, each with one cpu, 2+ gb of mem, and one SCSI channel with 4 disk on it. ( I KNOW, I KNOW, horrible design, not my fault, the "ENGINEERS" decided on that).
Anyway....
When I run sar -a 2 5, I get the dirblk/s at 80,000, to 90,000 on one of the partitions. The system is running IBM/Universe. I only get this when the Universe Admin runs a compare between 2 files, then does a few writes, and a few reads. The cpu is at 30-40%, and the disks are about 20-30% utilized. My question: Why so many dir lookups, if the "process" is only opening 2 files?
