Thanks for the suggestion Jiri. So far I have been monitoring sr and I know that the TCP async implementation might resolve some problems we're facing with kamailio.

But I'm a bit conservative and I want to do several verifications of sr before doing the "switch". So for now we stick to kamailio.

Does this TCP supervisor process priority sounds familiar to you for tuning kamailio ?

not really -- I sort of think that studying tuning of something what is overdue
for an update may cost you lot of time and bring less results.

       Hi

       I recently read the following in order to optimize OpenSER in
       handling
       TCP connections:

       "First, the TCP supervisor process must be given an elevated
       priority
       level in order to prevent anomalous behavior due to the Linux
       scheduler."

       First of all, as this is quite old paper (it refers to OpenSER 1.2),
       I'm wondering if such a tuning is still needed for Kamailio 1.5
       branch
       ? If yes, how can I do this ?
