Speed of file transfer

Can somebody have a real look at the speed of the file transfer.

It has become slower and slower over time.

I see a nice note about improving performance on the latest build but clearly not for file transfer.

If i transfer a 500mb file it can take up to 30 minutes with Screenconnect.

With a competing product that also does the same it's less then 30 seconds.

(We have a 8 GB connection and the endpoint has a 1 GB connection to internet)
