When you upgrade to 3.4, you may find your system starting to use more swap again. That's because it may have reset the 'vm.swappiness' value back to the default value of 60. If you got lots of RAM, suggest you change it back to a low value (like 10).
Do a 'cat /proc/sys/vm/swappiness' from a terminal to check its value.
