running with 250k IPsec tunnels (DH group 1, Encryption algo: AES and integrity

Multi-Core MIPS64 Processors with 16 cnMIPS64 v2 cores (one acts as an IKE
initiator and another as an IKE responder). We are running strongswan in both
systems. Both the systems have 1Gbps Ethernet cards, which are connected to 1
Gbps L2 switch. The Wind River Linux runs on all the 16 cores.</font></div><div><font face="Times New Roman">

missing something? Please note that, if I use 10 milli-second delay, it works
