We are migrating to HP UX-11 from Sun Solaris 2.6 and are finding I/O to be real slow at the OS level on HP. We're using Oracle 8.0.5.2 and 8k block sizes (dbblockbuffers). The Sun system uses 7200rpm disks and ultra scsi, the HP uses their FC60, fiber channel and 10k rpm disks. On both Sun and HP we are using file systems, not raw partitions. I'd think that the HP IO system would be faster, but it's much slower (35-50% slower).

Does anyone have any ideas on what to check or do? thanks
