Hi
I have a Turris Omnia :
Turris Omnia - rtrom01
Turris OS version 3.11.2
Kernel version 4.4.169-7bc33afbb1b35f5830b2b1b42c9cd8a0-2
There is a significant performance degradation when i install pakon or device discovery (so everything that is somehow connected to suricata).
The config on the omnia is very simple…it’s basically a NAT box…
So without pakon and/or device detection i get a throughput of cca 940Mb/s (TCP L4) that is the max that the interface can handle.
But with pakon enabled or device discovery I get speeds around 600Mb/s (100Mb/s more or less it fluctuates a lot).
is this normal ? I know that suricata is cpu intensive…but cca 30% is quite a lot
