Proxmox LXC slowdown network

[sabri]

Hello,
For almost 2 weeks, I noticed a slowdown network from the LXC.

When I test the HOST:

• (Paris) [1.88 km]: 4.834 ms
• Download: 927.20 Mbit / s
• Upload: 526.63 Mbit / s

When I test from the LXC:

• (Paris) [1.88 km]: 846,644 ms
• Download: 0.15 Mbit / s
• Upload: 0.00 Mbit / s

The HOST server config:
Intel Xeon D-1520
4c / 8t - 2.4GHz / 2.7GHz
64GB DDR4 ECC 2133 MHz
SoftRaid 2x2To
250 Mbps bandwidth
VRack: 10 Mbps

I only have 9 LXCs running.

A solution can be?

Possibly a configuration issue (ip-addresses, routing) in the container(s)?

Will be clearer when you post network configuration of both Proxmox Host and Containers.

For Proxmox Host:
file /etc/network/interfaces

For Conatiners
file /etc/pve/lxc/<container-id>.conf in Proxmox host and
file /etc/network/interfaces (or equivalent, depends oh Linux distro) in Container

as well as possibly added manual configuration for Ip and routing.
