Comment 61 for bug 595047

One more observation from another experiment I did:

I have swap on the same encrypted LVM as my root partition. Disabling swap makes the terminal launch much faster while copying -- still slower than when not copying files, but within a few seconds of clicking instead of within minutes.

However! Now, instead individual running processes (like Firefox and vim) hang much more agressively and frequently during copying. I'm not sure what to make of this, but I hope somebody who actually knows something about the Linux kernel will find this useful. :-)
