So, only a few per second? MyISAM can usually handle hundreds, maybe thousands, of _simple_ queries per second.

MyISAM locks the entire table whenever a write happens. InnoDB does not.

That implies finding ways to speed up the slow queries.

Strange. Could you show us the exact SELECTs you tried, together with EXPLAIN PARTITIONS SELECT... for each.
