Windows OpenVPN SSL Remote Access VPN Slow But MacOS Speed Is Fine

Question

Hi, 
 XGS2300 (SFOS 19.5.2 MR-2-Build624) 
 We have a bunch of Macs and a couple Windows 10 PCs. The Remote Access SSL VPN Works great on Mac. With a 500/500 connection at the office I get 300-350 from my home on MacOS in speed tests to a server in the office. 
 But a PC from the same location, with the same configuration file and credentials, the speed drops to about 40mbps. I only have a couple PCs, so they're not even on a domain (yet), just manually configured. I've tried changing the wifi from Public to Private and tinkering with other settings such as UDP/TCP, etc. Is there some hidden windows setting or registry entry that drops VPN traffic to a crawl? 
 When not on a VPN, speed/traffic is as expected. 
 Thanks.

Is the download via an https based URL? If so, this may be a known issue. If you file a support ticket we can help establish if it is indeed the same one and provide a patch until the fix is released.

When you look at your VPN adapter speed in Windows (when connected) you will see the real reason for your problem ;-) 
 You can have 5000 Mb/s connection, on Sophos Connect with Windows you will never have more speed as the VPN adapter has negotiated.
