There are a number of ways to speed this up.

For large inserts it’s usually the index updating that slows things down. So even using techniques like locking the table, turning off index updates, it can still take a long time when the indexes have to be created. Index creation, and thus inserts, on MyISAM tables can be sped up by increasing the value of the key_buffer_size. Make this large enough to hold the index(es) and your inserts can speed up by orders of magnitude. You can reduce it after the insert if need be.
