First thing, <swap> partitions are not mounted, so you should not see any
/swap if you run 'df -h'.
Swap space. The problem is that, when I issue the top
command, it shows that
used swap space is zero & my Physical Memory is 70% used. I think it's
pretty high since I don't use any software which is heavy on system
requirments. I tried the swapon command but in vain. Even eding the
/etc/fstab file didn't help. Is there any way to force swapping of memory ??
You should not. Swap is not like actual memory, it is just bare
unformatted partition on you harddisk, which is used by the kernel swapper
to place 'pages' of memory that are not immediately required for
execution. Since this involves disk i/o it is very slow compared to RAM.
The Linux kernel will begin swapping when it finds that it is running out
of RAM space, idle processes are also swapped. All this depends on the
priority of the process as well. For more discussion, see here:
Please enlighten .... Thanx in advance ...
