On my resent reload of knoppix it's taking quite some time to do simple cat commands. Like when I do this: cat /var/log/syslog |tail -60
it takes a while to actually list. I ran an updatedb. I never had this problem before even when I had 128Megs on my laptop. I'm now at 256MEGS.

So, I'm wondering what might be causing the delay and what the linux equivalent of a scandisk/defrag is. Thanks
