Has anyone run into situations where the avg blocks per read against their temporary tablespace seemed extremely low? We have a database block size of 32K, yet I'm seeing blocks per read on TEMP 5.2, on average. I would expect much, much higher, at least in the 20's. Is this a realistic expectation? I'm running 9.2.0.4 on Tru64 5.1. Thanks.
