For the first day after a reboot, our Universe application seems to be extraordinarily slow; dramatically slower than what I've seen on other systems, and maybe worse than how this system used to be after reboots (subjective assessment).
For several hours after reboot users weep and gnash their teeth over the slowness . By the end of a normal workday things seem to be back to normal. I *think* the performance improvement is gradual during those first several hours. The important thing to note is that there are generally no performance complaints -- except for after a system reboot. Poor performance after reboot is predictable. Fortunately, reboots are few and far between. Has anyone else seen this sort of thing? I'm fishing for ideas here. The only thing I can think of has to do with loading buffer cache. A stable system that has been running for a while would tend to have that day's current data cached, eliminating many disk reads that would be needed on a freshly booted system. But I don't know, it seems quite a stretch as an entire explanation. Some relevant info: HPUX 11i UV 10.0.16 8GB buffer cache ~ 300 UV processes No other application, except services supporting the UV based ap. ~ 30GB of UV data in active data files. Files are well sized (thank-you FAST and type 30), although some have huge data records that have outgrown original design. Typical application with typical mix of updates / reports. RedBack used heavily, with slowdown there, too. Again, any suggestions must speak to the difference between speeds of newly-rebooted vs. a stable system, not just general performance tuning.
