I noticed that around '71 disk buffers (or call it cached data) go a=20
bit too low sometimes. Then response time can be bad. Maybe there are=20
some tuning measures?
BTW. Wondering about the rising temeratures in spring, I wonder if a=20
code freeze is still possible. Maybe we should try it one more before=20
it gets really hot ;-)
