Two suggestions:

1. Find out where it is blocking -- is it disk I/O, memory, network (may
not be involved) or just MySQL? If, e.g., 'top' shows low CPU util. and
free memory, and the network's not involved, try #2...

2. MySQL seems to me to be a likely culprit. The default configuration
was never meant to be beat upon with a 64K record import -- search the
archives for high-load MySQL configuration, or use good old Google.
