Re: Sudden drop in read performance
I recreated the table using the InnoDB engine which is defiantly faster. Queries are coming back in 3 to 4 seconds rather than 10 to 13 but still not as fast as before.
However I also dropped and re-created the primary key and index on the original table which using the MyISAM engine and queries are coming back as fast as they used to.
Do the indexes need to be rebuilt occasionally on MyISAM tables?
