1. Ubuntu 10.04 64bit
2. No swap partition
3. JFS file-systems
4. / and /home partitions
5. sysctl -e swappiness=0
I can copy files around until my hearts content without any visible degradation in performance. I open up terminals and new firefox sessions.
For my main test I use a compressed /var/cache/apt directory. Comes in at around 4GB. I copy it twice simultaniously on the same partition and then between partitions.
This leads me to suspect it's something with swap space being used as memory and a journaled file-system colliding.
For those that are interested.
