If you mean that queries are processed slowly - you should probably add some indexes.
CREATE TABLE crd_favorites (
id int(11) NOT NULL auto_increment,
uid int(11) NOT NULL default '0',
cid int(11) NOT NULL default '0',
sid int(11) NOT NULL default '0',
did int(11) NOT NULL default '0',
PRIMARY KEY (id),
INDEX(uid),
INDEX(did)
) TYPE=MyISAM COMMENT='[Cartoes] Relacionamento entre cat, sub e dat';

Could you please tell us more.
