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 ?

I suggest you consider the sip-router core. There has been (and I think
still will be) tremendous effort put in it.

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 ?

Pascal
