[SR-Users] tcp_max_connection to 4096

[Vitaliy Aleksandrov]

You shouldn't feel any performance issues after increasing tcp_max_conn 
to 4096. Connections hash table size is pretty high (1024) so it's not a 
problem at all. Of course if you want to handle twice bigger number of 
simultaneous clients you need to check if you current hardware can 
handle it (RAM, CPU).
