Run 'top' to check what processes that hugs your memory or CPU.

In my experience, slow typing, when on a remote terminal, can often be caused by a duplex mismatch

try this:

ethtool eth<number>

for the number of your ethernet devices. If the switch is set to auto but you are set to full or vice versa, that can often cause a mismatch.
