See here: CHR and Proxmox bandwidth issues - #19 by mwf
I have about 10x times better performance with my 25G and 50G network (about 85 to 90% what I expected). I’m super happy with that.
So, for every other guy with the problem: Just update to ≥ v7.20 and give it a try
Edit: I did another few tests.
Setup:
- 3x Proxmox Cluser. Hosts with a 2x25G mlx5 card
- Configured as OVS bond in a OVS bridge
- The CHR sits in a VM as main router/gateway (with firewall rules & NAT)
- CHR manages all the traffic between 15 VLANs and a 25G ISP uplink
- Network behind is based on CRS504 and other Mikrotik devices
Results (between VLANs and also to ISP):
- v7.18.2 = 2.5-3.0 Gbps
- v7.20 = 22.0 - 24.0 Gbps
