Hello, I have recently (within the past few months) turned up an MPLS PE on a 1Gbps link in a L3VPN configuration with BGP and RDomains. I'm seeing some strange throughput numbers that I am seeking to get some help understanding.
Now I am currently running OpenBSD 6.4 on the particular PE, and I realize that 6.5 has several MPLS updates and fixes, I have a maintenance window scheduled in a couple weeks where I'll be upgrading this particular system. Here's what I am seeing, with iperf: on flows that ingress the MPE interface I see around 750-900Mbps @~20k pps. for flows that egress the MPE interface, I see around 200Mbps @ ~2k pps. I realize that things like "throughput" are highly variable, but as I troubleshoot this - I am looking better understanding how and what is at play within OpenBSD itself, be it CPU limitations, etc. as I haven't ruled out the rest of the infrastructure at this point. Thanks for any insight you can provide.
