actually I haven't yet.
I have noticed that during the time the query 
executes there is neither so much CPU load nor network (communication 
with db) load. The client seems to hang, then after a minute or so the 
query returns data.
I also thought this problem could be related to db 
encoding but changing it didn't help at all.
If it's a client-related 
problem, I can't understand why such different clients behave the same
