I have been troubleshooting plex playback issues for a couple weeks. Plex playback involves lots of pauses and slow starts. I have seen the same performance when using plexdrive or rclone cache.
Using rclone copy I can move data to and from googledrive usually between 12-25 MB/s

Using rsync to measure speeds while copying from an rclone mount I see speeds in 1.2-5.5MB/s

I am using rclone encryption. The system has 16GB RAM and 2 virtual CPUs. I have seen similar performance on different cloud provides (ssdnodes, chicagovps, digital ocean). The VMs do not seem resource constrained. The size of the google drive mount is about 11TB.
Rclone mount command being used
/usr/sbin/rclone --config /root/.config/rclone/rclone.conf mount --allow-other --stats 10s --buffer-size 1G --timeout 5s --contimeout 5s --cache-db-purge local-crypt: /mnt/media -vv
