Description

I have this use case where I am using mirror.exe to mount some remote network shares as local drives on a Windows 11 VM. The shares are connected to via WireGuard VPN and the performance when copying a file via the explorer (without Dokany) is the upload limit of the remote connection (around 40mb/s) but when doing the same operation through Dokany's "local" drive the performance maxes out at around 12mb/s. However, if I start multiple concurrent copies, I can achieve similar speeds to what I could with a single file transfer without Dokany. I was wondering if there is anything I can possibly do to improve the performance of this particular scenario. The performance penalty of using Dokany with a local network share is pretty negligible on the same machine, but this remote drive ends up chocking it.

I appreciate the help!
