will be affected.
There may even be a performance gain, since if the system comes under
memory pressure again, some of the in-memory pages of those long-lived
processes previously copied to swap may still be clean, and the system
won't even have to page them out; it can simply free the RAM. I can't
think of any way for there to be a performance hit, unless you actually
run out of swap.
I must really be missing something here..
My case. 384MB of RAM
For several days swap was 0.
That to me means that everything was fitting nicely into memory.
At one point in the last few days I must have opened too many
windows/apps.. and the OS actually had to use swap.
Once I closed programs (xpecially X, Opera, and other GUI apps) I expected
the swap would go back to 0.
Swap remained at 10MB.. Whatever processes are using the swap aren't they
accessing the HD?
Can there be swap usage, yet the OS doing all the work on memory?
