It took me 8 hours to look at about 30 web pages of a ecommerce site. I never was able to make my purchases. Sometimes, it would take 15 minutes to bring a page up. more ram is an easy answer, but this is an old machine, and 48MB is overkill for other work. what has changed?
Swap is normally managed transparently, so you don't have to do anything. I'd suspect your problem lies elsewhere. What does "cat /proc/meminfo" show?

The above shows you're using little more than 1/5th of your swap space, so that's not your problem. Top can show what processes are using the most CPU resources. Also bear in mind that a 133 MHz 48 MB system is not going to be fast, if you're running KDE or Gnome.

You have 45 mb real memory, and 97 mb of swap in use. More swap than real memory --> thus slow system. -- Cheers, Carlos Robinson

Oops! I was to fast, you are right. Yes, the above must be before he really started, I think. I remember higher numbers on my old system, like a hundred Mb or more for my 32Mb Ram! gnome would be a bit better, but I would use fwmn or similar. Kde is nearly unusable with that memory. -- Cheers, Carlos Robinson
