[SR-Users] Question about Kamailio Performance

[Dmitri Savolainen]

Hi.
In my tests the best perfomance was achieved with combination of mysql and
htable  as mysql cache (
http://www.kamailio.org/docs/modules/devel/modules/htable.html).
With SIPP testing it is important to switch off kamailio  logging (set
critical level for example) and check network perfomance (sipp and kamailio
should be within LAN)
