Hello everyone,
I am currently testing an ipsec site2site tunnel with my Edgerouter Lite and a Linux server.
The Tunnel itself is working, but the Performance is quite Bad.
With Iperf i get around 48 Mbits/sec, while the CPU Cores are running at 100% with ksoftirqd using most of the ressources.
I Think the Hardwareoffloading is not working, but it should be enabled:
$ show ubnt offload IP offload module : loaded IPv4 forwarding: enabled vlan : enabled pppoe : enabled gre : disabled IPv6 forwarding: enabled vlan : enabled pppoe : disabled IPSec offload module: loaded Traffic Analysis : export : enabled dpi : enabled
