Details - Hi,

I am experimenting with the the db_mode parameter of the USRLOC module. In my scenario I am firing approximately 300 unique registers per second at a kamailio instance running on a dual core machine with a local mysql db.

db_mode = 1
Some of the the registers are running in a timeout, so I think this mode is to slow to handle the load.

db_mode = 2
There are a lot of timeouts when the module is syncing the location to the database. With ~ 80000 contacts the syncing takes about 30 seconds, meanwhile kamailio is not responsive. I've tried the timer_procs parameter but it doesn't help. Is there something I can to to make kamailio more responsive during the syncing process?

db_mode = 4
Works fine, but requires some external tool to write the contacts in the database.

Regards
Krischan
