Description

Windows build number: 10.0.19041.84
Dist: Ubuntu 18.04 LTS

I just installed WSL2 on my home computer for the first time and something i notice that i don't see on my work computer is that WSL2 has dramatically lower network speed (wget or git clone tested). Speeds on WSL seem to be about 10-20 kb/s wheras windows download speed seem to be correlating to my ISP spec of 100/10 Mbps or above.

Research direction

Start by reproducing the reported 10–20 kb/s transfer speed in WSL2 with wget or git clone on the listed Windows and Ubuntu versions, then compare it with the Windows result. Done means identifying and correcting the WSL2 networking cause and verifying that transfers approach the host connection speed.
