Hmm, that sounds a bit crazy .. although the windows VM does suck so who knows :) > 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.

I meant JavaMem. Looking at > the task manager, I'm not seeing any paging per se, so I don't think > that is it. It seems to be a periodic task that freenet itself is performing. Hmm. Tried useDSIndex=false? I don't know if that's particularly significant though. You could also try doLowLevelOutputLimiting=false / doLowLevelInputLimiting=false if you make sure doCPULoad=true and you have an outputBandwidthLimit set, that's more of a CPU thing but it seems to reduce load on my node. Other than that give Java a lot of memory via the control panel->Java -Xmx method and also set -Xms reasonably high to reduce fragmentation / management overhead. If you don't run Frost or other Java apps on the same machine you could make -Xms the same as -Xmx. Or install one JRE just for freenet and one for other apps and set the flags per instance. > It might go away if I dropped a drive in that had a decent cache. > This is a 5 year old 30GB maxtor drive, and I doubt it has much of a > cache on the drive itself.

You might even consider EVM to split your DS across multiple SATA / SCSI drives :) This is suprisingly easy in Linux, I have no idea how to do it in windows (possibly you would need 2003 server or something.)
