Higher ping response time

[mhaluska]

I found my virtualised OPNsense has higher ping response time then my Mikrotik hardware, 20ms vs 26ms (tested from Hetzner VPS). So I deployed another virtualised OPNsense with same config and same Proxmox machine as first one (except few virtual intefaces and less RAM), WAN interface with own public IP and one local LAN.

And results are:

OLD
20 packets transmitted, 20 received, 0% packet loss, time 33ms
rtt min/avg/max/mdev = 24.705/26.418/32.959/2.252 ms

NEW
20 packets transmitted, 20 received, 0% packet loss, time 45ms
rtt min/avg/max/mdev = 18.805/19.683/26.816/1.707 ms

Configuration is same, offloading disabled, ICPM echo reply allowed as 1st rule on WAN interface. No traffic shaping queues. Tried disable firewall on OLD one, same results.

Version: OPNsense 20.1.6

I've no idea what can cause this 5-6ms delay. It's not causing any issues, but I'm curious why.
Some idea?

If possible please move this post to General Discussion, I just realised I used wrong one. Thanks
