The kernel 2.6.24-17 does not help. I think it's becomes even worse with the new kernel. I tried Debian Lenny and Fedora Core 8. The problem exists in these distros too, but it's much better than in gutsy. I am using ext3 in journal mode. I tried xfs, but same problem. I had never performance problems with ext3 under feisty.
Hardy is unusable for me. It's fine for surfing, writing documents or reading pdfs. It's awful for working with vmware or disk intensive apps. I just finished a backup (2.6.24-16) with rdiff-backup (pybackpack) on a local usb2 harddisk. I think it's related with this problem. Here is the log.
