Online performance and Multiprocessors.

Hi, I know next to nothing about administering Online, and my users are complaining about the database being slow sometimes. Could some kind soul outline the simplest method for indicating whether putting an extra processor and/or extra memory would solve the bottleneck? I have tried using onstat -g gloas stated in the manual but the output means nothing to me. The OS is currently using less swap space than it has RAM, so I don't imagine that it needs more memory, and forking out 5 grand for an extra processor is quite a lot if it doesn't make a bit of difference!! I have read about binding online to use an extra CPU exclusively - does anyone know if this is possible with Solaris 2.5, and if so, does it work? Does it improve performance significantly? I expect that the biggest performance gains would arise from correct structuring of the database, indexes etc - I unfortunately don't have any input on that side of things - I am just the lowly sysadmin and it's my fault that it is running slowly! I am running Online 7.1 under Solaris 2.5 on a SS20 with 64Mb RAM and processor. Thanks in advance, Richard Hewitt
