COUNT(*) for Innodb Tables
I guess note number one about MyISAM to Innodb migration is warning what Innodb is very slow in COUNT(*) queries. The part which I often however see omitted is fact it only applies to COUNT(*) queries without WHERE clause. So if you have query like SELECT COUNT(*) FROM USER It will be much faster for MyISAM (MEMORY and some others) tables because they would simply read number of rows in the table

Force index with active record find Â« Jason Watkinsâ€™s Weblog
A small useful tip: Mysqlâ€™s query planner occasionally has trouble picking the right index. Iâ€™ve found that normally if you try variations long enough, eventually you find a way to do the right thing. Recently however I ran into one I couldnâ€™t coax. No big deal you say, after all, thatâ€™s what find_by_sql is for no? Only probl em is, the query in question was inside a with_scope block, and I really
