[kwlug-disc] upgrading hardware/64bit OS

You should be able to upgrade to 4GB RAM without any software changes,
and see a difference, if there is a difference to be seen. i.e. If
it's, or the machine, is memory starved, this should get you over a
hump. One vm with 4GB RAM hard, 2GB for VM, should be more than
sufficient no matter how much memory you have. i.e. If not running
multiple more vm's, 4GB would be sufficient - 32/64 bit won't be an
issue, and more RAM isn't going to help.
Since it's a vm, you could try it on different machines you have, and
see to what extent you see a performance gain. e.g. More RAM on one
machine vs. a faster CPU on another.
FWIW, on a Windows machine, virtualbox was so slow I went back to
vmware player. YMMV. You could try this vm under windows and just peek
if there are any noticeable performance changes.
Any 64 bit OS can vm a 32 bit OS, but the reverse is not true. You
could also run the vm against physical disk partitions. (Not
recommended for Windows - it gets very unhappy at the hardware
changes. But if you only ever boot it that way / the vm hardware
doesn't change, you'd be OK.) [hw change as in dual boot AND vm boot.]
So, you could copy the vm to a usb key, go to different machines, and
see if you can spot a difference. For that matter, I suspect with a
live cd and this vm on a usb key, you could walk around trying
hardware / speed.
Do you have any sense as to the cause of the slowness? Is it lack of
memory, are you CPU bound, is the video slow?
