Issue #3298
strategies to improve strongswan performance per single SA
Description
hello,
Im searching for the ways to improve performance System interrupts and load balancing between multiple cores/threads.
so far this command seems lower CPU by ~5%. - tuned-adm profile network-throughput,
tried to improve the RPS: by command:
echo "fff" | tee /sys/class/net/p1p1/queues/rx-{0..11}/rps_cpus
echo "fff" | tee /sys/class/net/p1p2/queues/rx-{0..11}/rps_cpus
echo "fff" | tee /sys/class/net/p2p1/queues/rx-{0..11}/rps_cpus
echo "fff" | tee /sys/class/net/p2p2/queues/rx-{0..11}/rps_cpus
after this the load started not loadbalancing between cores, but the process itself started to jump beetween all cores.Any more suggestions ?ThanksRelated issues

I'm planning to try increase default queue counf from 12 to 64.
sudo ethtool -L p1p1 combined 64
sudo ethtool -L p1p2 combined 64
sudo ethtool -L p2p1 combined 64
sudo ethtool -L p2p2 combined 64
and to try to swtich off the
TSO and GSO features.
Maybe you have any other recommendations ?
ethtool -K [] tso off
ethtool -K [] gso off
