Slackware 64 1337, slight delay when processing commands using Bash shell

I upgraded from Slackware 64 13.1 to Slackware 64 13.37 a week or so ago. I am now having a perceptible delay of a few seconds when launching commands from the command line, say for example: screen -R.

My laptop is an X200 with 3GB of RAM. I know its only a small issue and doesn't really impact at great deal, but was just wondering if anybody had any ideas why the delay would suddenly start after upgrading..

Does this happen when you are using X and writing commands to a terminal emulator or before you log into X?

When I am using X, I have been investigating further, its either wicd or firefox 4 that is causing the problem. Every so often the hard drive writes continually seizing the machine up.

My money is on Firefox 4 causing the issue.

Try running top (or htop) in terminal to see what's eating up your processor time. Repeated writes to the disk could be causes by you running out of RAM. But you should see slowdowns on your entire computer not just the command line ...

I didn't use my laptop for over a month whilst I was overseas. Would it be say cron jobs queued up?

Nothing is hogging the cpu and my memory is approx 500mb / 3GB with no swp being used.

I have certwatch, logrotate and slocate in cron.daily?

It doesn't seem so bad now and my hard disk hasn't locked up for a while, I guess Ill have a root through the log files to see whats up.

I wonder if it could be your hard drive spinning down (by itself or by the kernel) when idle.

Maybe try another terminal program or two (say xterm) and maybe try another shell. I don't really have any clever ideas ...
