How does TIM handle open connections? A high number of open connections can impact TIM performance.
TIM needs to see all the TCP/IP packets from SYN to FIN to complete the connection process. If there are any TCP sessions that have not finished this connection process, then TIM will wait for additional packets before it times out based on the condition described below:
Otherwise, TIM uses:
