Weird. node.db4o was an insane 375 MB. I deleted it and and added a bunch of downloads. Now it is less than 10 MB. That definitely helped some with the disk thrashing. I think I found the main problem, and I'm embarrassed to say apparantly I had xmlspider plugin running and writing GB+ files to the same disk the node resides on. I turned this off and the disk usage became manageable. I also upgraded my HDD from an older 2 MB cache model to one with 16 MB and now Freenet is zipping along nicely. I did see some errors in the log so I am sending it to Toad for review. P.S. I would recommend not installing the xmlspider by default on installs. Victor - might this be your issue as well? -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Use GnuPG with Firefox : http://getfiregpg.org (Version: 0.7.5) iEYEARECAAYFAkoDvJMACgkQ4esu1mlKOs9TxQCeJmhz1SP4Qu2Y0RgK3V2Kyl/p ALoAnikDQ/ki8CAAy0+rYnqKHrIBWiqQ =9hlX -----END PGP SIGNATURE-----
