Hi Richard,
The consensus best
practice is to have enough RAM that you don't need to
swap. If you need to
swap, your life will be sad no matter what your disk
config is.
From my understanding Solaris does not overcommit memory allocation, so every
allocation must be backed by some form of memory (real RAM or swap). Some
programs tend to allocate more memory than they actually use, where unused
memory is mapped from swap without any I/O. Without swap this would be drawn
from real memory stealing memory from other applications or the page cache. A
big swap is therefore helpful even if there is no swapping activity.
Is this implemented differently in Solaris 10/Nevada?
warning: noun/verb overload. In my context, swap is a verb.
