IMHO the generic answer for tuning problems is always: (1) Identify the #1 bottleneck (2) Fix it (3) Now bottleneck #2 has gotten a promotion: If you still feel the need to continue tuning, continue at (1) The bottleneck might be: # CPU (in which case you might be out of luck with a 3rd party application) # Memory # I/O # Database (a specific case of I/O) # Network throughput, latency or anything else, e.g. other backend systems. Sorry, this is pragmatic, but might not be too helpful. It's the long form of the consultant's standard answer "it depends".
