I'm helping a new member in Spanish forum. I never work with this hardware. May be I miss some information to ask. Opteron 2.2 Ghz, 4Gb RAM, windows 2003 sp1, sql 2000 sp4. /3G. After 2 days or sql start up (they have to reboot because performance) this are the numbers: Pages/sec: Average 1000, max 4000. Processor: average 97%. Avg. Disk queue length: 5. After reboot and for 2 days: Pages/sec: Max 120. Processor: 40% Avg. Disk Queue Length: 2 SQL server dedicated, Maintenance Jobs not optimal but reasonable. I suggest to run Profiler, reindex, etc. And, of course, talk with developers about long queries found with profiler. Anything else?
