mysql performance / tuning

Hello everybody,
general question on performance,

I have a Perl-DBI program that is currently taking a total of 13 hours and using, at its peak, 3Gb of RAM. Compressed, the db files take 40Mb of disk space and a couple of years ago it used to take up 20Mb ; at that time, the program (which was a bit simpler) used to take one hour a to complete.
I am running MySQL 3.23.46 and Red Hat 7 on a dual P4 ~1GHz with 4Gb of RAM.

I have run myisamchk -m <db_name> without avail.
just wondering if there are any tricks/tools besides:
- mysql-super-smack,
- the different cache sizes,
- explain plans,
- print statements.

thanks !
Tommy
