performans problems

Hi
I'm using Catia V5 on Sun solaris 9 on Sun Blade 2000 WS with 2 CPU's and 4 GB ram, but I still performans problems. I always get memory problems and the cpu's aren't used effectively when ever I try to run complex assemblies with catia v5. Is there any tuning needed that I can to have more performans.

Nukfor makes some good points, but it is important to note that the reason I espoused more swap space was not for the swap itself, but for the tempfs.

The lack of tmp space (which uses tempfs) caused by the lack of swap space (the source of tempfs space) could make it look like a memory problem, when it is actually processes not being able to write tmp files.

Lots of system processes use tmp, including nis+ which is why one of the symptoms of insufficient tmp space is the loss of ability to login.

Another fix, if you are concerned about the performance of swap, would be to mount /tmp as its own partition with a lot of space, which would take care of Nukfror's concern, since it would only be used for tmp, and not swap.

Solaris is smart enough to know when it needs to swap, but if the resources are not available, then it can't. With 4 ig of memory, you shouldn't be having memory problems unless you have a memory leak...
