Many categories - tip to improve MySQL performance
Posted by Esvon Support on 22 June 2012 11:02 AM
If you have many categories (hundreds, thousands) and your classifieds software version is 4.0.11 or less,
run the following SQL statements from Admin Area -> SQL Command
(replace "ec4_" with your tables prefix):

ALTER TABLE ec4_category DROP INDEX name;
ALTER TABLE ec4_category ADD KEY name ( weight, name(5) )
