If you are searching with %pattern%, your speed is depending on the speed of table-scan. The speed of tablescan depends on your my.cnf setting (increase record buffer size?) and how big your records are.

Maybe you can still use fulltext search for general cases; and use pattern match ONLY when you are searching for 3-char-term. You should be able to make such "Switch" through your interface.
