anna, did you have a chance to check if ude_presentity index could be removed as redundant from presentity table? according to section 7.4.4 of mysql 5.0 reference manual an index on columns (a,b,c,d) automatically contains also indexes on columns (a), (a,b), and (a,b,c). so i would like to get rid of ude_presentity index if it does not add any value.
