There are lots of things to check. Please provide these so I can zoom into the answer:
* SHOW CREATE TABLE tbl\G -- engine, indexes
* SHOW TABLE STATUS LIKE 'tbl'\G -- sizes
* EXPLAIN SELECT ...\G -- clues of inefficiencies
* SHOW VARIABLES LIKE '%buffer%'; -- cache size
and surround them with [ code ] and [ / code ]
How much RAM do you have?
InnoDB can handle huge tables. In 5.5, it generally handles them better than MyISAM.
TRANSACTION settings are ignored by MyISAM.
