Description
On installations with more than 2.500 mm-relations in sys_category_record_mm the performance is getting very low.
Adding MySQL indexes to uid_local and uid_foreign fixes that.

There are indexes present:
master has
CREATE TABLE sys_category_record_mm (
uid_local int(11) DEFAULT '0' NOT NULL,
uid_foreign int(11) DEFAULT '0' NOT NULL,
tablenames varchar(255) DEFAULT '' NOT NULL,
fieldname varchar(255) DEFAULT '' NOT NULL,
sorting int(11) DEFAULT '0' NOT NULL,
sorting_foreign int(11) DEFAULT '0' NOT NULL,
KEY uid_local_foreign (uid_local,uid_foreign),
KEY uid_foreign_tablefield (uid_foreign,tablenames(40),fieldname(3),sorting_foreign)
);
6.2 has
CREATE TABLE sys_category_record_mm (
uid_local int(11) DEFAULT '0' NOT NULL,
uid_foreign int(11) DEFAULT '0' NOT NULL,
tablenames varchar(255) DEFAULT '' NOT NULL,
fieldname varchar(255) DEFAULT '' NOT NULL,
sorting int(11) DEFAULT '0' NOT NULL,
sorting_foreign int(11) DEFAULT '0' NOT NULL,
KEY uid_local_foreign (uid_local,uid_foreign),
KEY uid_foreign_tablenames (uid_foreign,tablenames)
);
Which queries are slow? Please post examples.

Sorry, my fault, you are right. I don't know why, but somewhere those indexes got lost in my installation. Did a compare and they are there.
Thx for your help. Please close.
