enabling swap space takes long time
hi
am using rhel 4
when i boot the system it takes nearly 15 minutes to boot up
it takes too much time in enabling swap space...
what is the reason for this how to solve it..
and after the boot up ..if i open any application it takes 1-2 minutes to respond...
i checked all disk partions ..all are correct...
/etc/fstab file also correct..what is the problem ....?

What's the hardware, how much RAM, how big is swap?
Anything odd in dmesg' output? The logs?
Cheers,
Tink

People might be able to help you more if you sent what is returned by
cat /proc/meminfo
free -m
and ps
you can also use
top
then hit
shift-M
to see how the memory is being used
Sometimes people boot with "linux numa=off" if they don't need it, and it speeds things up.

Swap is WAY slower compared to RAM. Be happy if the system doesn't swap.

Merged your two threads on the same subject; please don't
do that. Double posting is bad, and against the rules.
Btw, you didn't answer even half the questions in the
first thread you kicked off ... if you want us to help,
help us by answering requests for more input.
Cheers,
Tink
