Hi,

I made these kinds of tests before. I have two tips for you to pay attention to:

1. Read about the [routes] on SIPp, It is tricky to satisfy kamailio with SIPp scenarios.

2. Make sure your DB table is well build (use less varchars and more integers).

I found out that there are many kamailio modules I can use to load data in to memory and I hardly use the DB (only for ACC). I use MTREE, HTABLE, DIALPLAN, CARRIERROUTE, DROUTING, and so to store the information I need. And I get it with the simple functions of the module.

I load around 6 million numbers and other data which takes about 1.5 Gb of the memory.

For getting around the real-time changes that I need to deal with (In DB the data changes are immediately made on your service…). I have a RTIMER every 120 sec that check is a reload is needed. If so, it reloads the relevant data (very fast).

BR,

Uri

if you do a lot of direct DB interactions, perhaps latency of the
queries will be relevant. You can use benchmark module to see how long
it takes to execute part of the config file.

I think you don't fetch lot of records from db in config, so memory
should be no problem, however you can dump private/shared memory usage
via RPC commands within sercmd cli. CPU is a good metric always and easy
to watch with systems tools.
