By watching the traffic on my server, I noticed that NetDrive uses HTTP/1.1 only; it doesn’t support HTTP/2.
In my testing using the built in Windows WebDAV Redirector client, I observed a performance improvement of ~50% when downloading and 60% when uploading using HTTP/2 instead of HTTP/1 with no other changes (same server, same client, etc).
Is there a plan for adding HTTP/2 support for NetDrive?
