Speeds to an Rclone mounted, encrypted gdrive on Windows

When I send to my encrypted gdrive using Rclone or Rclone Browser, my pipe is usually maxed out and transfers always complete.

If I try and send to that same Rclone drive using Windows copy or Goodsync, it only works if sending multiple tiny files (documents) or large single files, individually.

But try and send 8-10 smaller files at once and either the speeds are terrible, or the transfers never complete.

Is that a technical limitation of Rclone Mount?

The mount was created with nssm.

Google Drive only allows you to create 2-3 files per second so the speeds of many small files are terrible. You can't tune around that other than compressing them up. It's not a rclone limitation but a Google Drive API limitation.
