Yes there is a lot going on and a lot using memory. I normally have about 20% to 25% of my Gig of swap used... meaning that I have allocated roughly double my RAM in applications. And when this worst-case happens, memory is full... but the only active application is Netscape. On my home machine, the same thing tends to happen. It only has 128M and vastly fewer things going on. I see cases were I'm surfing for 20-30 minutes and I will hit this 10 to 30 second (longer, becase the swap at home is slower) gap in netscape response. The only other applications running would be something like a small UUCP transfer or a small amount of NFS traffic when the wife's (diskless) machine changes screensavers.
