MTU Option

Optimizing Network Performance with MTU Settings

Hello Noez Community,

I wanted to share my recent experience with optimizing network performance by adjusting the MTU settings on my host system and virtual machines.

After setting the MTU option in the network settings of the host system to 1476 and configuring the VMs to inherit the MTU option from the underlying bridge (by setting it to 1), I observed the following results from various speed test websites:

  • Ookla: Ping 137ms, Download 396Mbps, Upload 3Mbps
  • Telekom: Ping 28ms, Download 303Mbps, Upload 926Mbps
  • Vodafone: Ping 28ms, Download 842Mbps, Upload 158Mbps
  • Fast.com: Ping 28ms, Download 570Mbps, Upload 930Mbps
