Slow VPN speed strongswan on FreeBSD

salon_sue

I put up a VPN server with strongswan 5.4.0 on FreeBSD 11.0-RELEASE-p1 on a RaspberryPi 2. So far it works fine, but the speed is varying and also much slower than on Raspian which I used before. Here is the configuration: /etc/rc.conf hostname="rpi2" ifconfig_ue0="DHCP" sshd_enable="YES" powerd_enable="YES" # Nice if you have a network, else annoying. ntpd_enable="YES" strongswan_enable="YES" pf_enable="YES" pf_rules="/etc/pf.conf"...

Great question — answering as the UphillTech team:

I just checked out Raspian again and I turned on parallel crypto. Now I get around 50 Mbps throughput. I think I can't achieve this with FreeBSD, so I will stay on Linux.
