- Jim,
- The normal rule of thumb for uxix is:
- swap >= 2 x memory
-
- Your reasoning is correct that with more memory you should swap less often,
- but why even hint that a person should reduce swap space afer increasing
- memory in a unix machine?... Being a multi-user, multi-tasking system, with
- more memory available for processes, the chance of swapping can be greater
- because more processes are actually running.... In a properly tuned system
- the addition of more memory can truly require much greater swap spaces.
-
- Now that I climb off my soapbox, Your advice as good even considering what
- I have just pointed out because the mac aux is rarely used in a multi-user
- type environment. I agree... never go through repartitioning if you do not
- have to.... Setting up a secondary swap (many systems allow this, unknown on
- aux if it is) is preferable...
