I would venture to say that increasing VM is more likely to increase disk access, not decrease it. -Xmx does seem to be what you want, though; it will set a ceiling on the amount of RAM that Java will allocate. Try disabling Virtual Memory in Windows altogether, and see if that helps any with the disk thrashing. You should be able to run Windows plus Freenet reasonably well in 640 megs, especially if you kill off any tray utilities and unnecessary services. Check the task manager to see how much RAM Windows wants for itself, then use -Xmx (or FLaunch.ini) to give Java most of whatever's left. s
