I have a strange problem:
Load average / CPU usage on server rising abnormally after 50-100 shared
roster groups added. Tested with db_type mnesia and odbc. I use
mod_shared_roster with odbc (mysql) right now. There are a lot of
"select opts from sr_group where name=XXX" queries.
Clients cann't get roster from server or getting it very slow. When i
truncate sr_group table everything is ok:( Cann't understand what's the
problem. Please help to find it.
I need to create 200k-300k shared roster groups with millions members -
is it possible?
