I agree with the principle of not using third party (on Windows XP) RAM management programs. But I have the impression that at certain times almost all of my RAM is used, in particular during/after the startup sequence of my computer. RAM usage surpasses 400 Mb, sometimes 512 MB. (I have 512 MB RAM, and I use a swap file). It's even worse now that I've blocked Counterspy in the firewall. I'm aware of the phrase 'not used RAM is wasted RAM'. But maybe it makes sense to 'flush' whatever clutter is in RAM and is not needed, in certain instances, like after the startup sequence. Any suggestions ? I use a swap file, default as under Windows XP Home Edition service pack 2. Does it actually make sense to use a swap file, should I change the size of it ?
