I'll put pictures because the copy paste breaks the table formatting:
fw ctl affinity -l -r
cpstat os -f multi_cpu (it's Sunday morning so not much traffic)
As you can see only the first SND (on the first CPU core) seems to be doing anything. The other SND (CPU 2/3 depending on the command) is mostly idling.
I suspect this may be because there is only one LACP bond interface (of two physical interfaces) on the gateway (but with many vlan subinterfaces). Therefore all the queuing of this bonding interface would maybe be handled by the first SND only, does that make sense?
If this is correct, I guess I should reconfigure CoreXL with only one SND?
It is an open server R77.30 gateway.
The SND/IRQ core is assigned to the physical interfaces, eth1 is being handled by CPU 0 while eth0 is being handled by CPU 2. 95% of your traffic is fully accelerated in the SXL path (and a relatively high templating rate of 49%) so higher CPU load is to be expected on your SND/IRQ cores, a few points:
