Because the sage.math hardware was physically broken when I did the upgrade on the temporary replacement for sage.math, so when we swapped back we got back the non-upgraded sage install. I'm fixing it right now. > > Also I wonder why the process that I'm running only gets 2% of CPU. > Not many processes are running at the moment. Is the I/O still a > problem? Yes. We have very large Sun Fire X4540 running OpenSolaris with zfs, and for reasons still unknown, the performance is horrible. Using a random $300 USB disk plugged into a laptop and served over NFS would give better performance (I'm not exagerrating). Obviously we wish to remedy this. Note that zfs does have some cool features, e.g., look at /home/.zfs/snapshot to see snapshots into the past of the filesystem state.
