Generally if you are making 3-4 calls for select/update/insert, a stored
procedure works much better compared to separate calls to database because
communication overhead is only once and database probably pre-parse-pre-plan
the queries in it. So yes, it does improve performance..

What's the query? Could you elaborate more on that?

And other applications are hanging is rediculous behaviour unless it's windows.
On linux, any 100% CPU chewing task should not block any other task. At least
2.4.19 onwards, same goes for other unices.. Windows is a different story.(My
mail client, pegasus maxes out CPU, if it can not reach SMTP host for some
reason. This is XP/SP1.. Go figure)
