Problem: When uploading from the web client, I can achieve close to 600+ Mbps uploading a single large file (50GB). However, when I sync from the desktop, using only one folder and the same file, the upload speed averages somewhere closer to 20 Mbps. This is orders of magnitude slower. Not sure if there are optimizations I'm missing.
Steps to reproduce
1. Upload single large file (over 2GB+ should work) over web client.
2. Delete and remove file from account.
2. Upload same file via desktop client.
Expected behaviour
Upload speeds for web interface and desktop client should be somewhat comparable.
Actual behaviour
Upload speeds from desktop client are a significant fraction of the upload speeds over web client.
