throughput with AES256

Description We are using p1021 processor with quicc engine , we are using UCC in fast mode as well as siram,si,tdm , we are using it in nibble mode. we are able acheive 100mbps data rate in our radio . p1021 does not have hardware encryption , so we are using strongswan package , ipsec for ppp interface in tunnel mode. userdata -eth1 --ppp0 of radio 1 air interface - radi2 ppp0 -eth1-userdata., My tunnel is in between ppp0 , aes generic mode I am using . Without encryption we are getting 100Mbps With Encryption we are getting only 50Mbps . , we want 100mbps throughput with AES(specification) We have only two cores and all our quicc engine peripherals are on cpu0 . After tunnel formation I did not see any traffic on charon threads . When I am giving traffic only I am able to see active ksoftirq , kworker , and our main application.

Dear @kandimallabhara,
Due the lack of hardware encryption it doesn't be posible to get the throughput you want. Considere use other MPU with the hardware encryption build in.
Let the CPU administration to the SO with that you will enhance the performance.
