[SR-Users] TCP Children and Connection Handling

Hi All, I'm facing an issue with TCP connection from Proxy(kamailio) to a SIP server on a load test, where kamailio is not processing the message fast enough and which leads socket buffer getting filled up. I have increased the tcp_rd_buf_size but that really didn't help. According to my understanding the each TCP connection is assigned to a TCP children, and TCP children will read until it there is no data for few seconds and return the connection to tcp main process. In this case the TCP connection is to the SIP server which always have some data due to periodic SIP ping ,registration refresh and calls etc. So i believe this connection will be hold always by one children and since that children is processing the message sequentially, it might not be possible to increase the performance on this connection. My question is, If my understanding is correct How do we increase the performance for a particular TCP connection? Does Kamailio has some mechanism to distribute the message from a single TCP connection to different child, when it is overloaded? What is the best way to solve this issue? Thanks in advance. Jijo
