Hello,
some confusion was created around this subject. It was pointed a news
which was related to an improvement (fetch support) which brought memory
usage optimization in usrloc (going to be expanded in usage to other
modules, like lcr, presence ...), not usrloc loading/lookup
optimization. It was not yet a news since the work is not fully
finished/well tested. The news about this new improvements will come in
the near future. It started in summer, with:
http://openser.org/pipermail/devel/2006-July/003469.html
Shortly, usrloc records are not loaded anymore by the main process, but
by first child. All other children processes can handle other events/sip
messages in parallel. Previously, at start, OpenSER was blocked until
all records were loaded, which could be quite long when having big
numbers of active users.
Cheers,
Daniel

Where is the
time saving coming from then?
I think the idea behind was the following:
The use case is for big providers with lots of entries in the usrloc
database. A restart in such situation might lead to stop in the
service for quite a few minutes (i don't recall the numbers) while the
server is loading the data.
If you split the data in chunks and load it sequentally, you can start
serving without interrumption...
please, can somebody confirm this assumption(I'm not 100% sure)??
Samuel.
