SFC - London speeds

I work from the US for an employer in the UK. They use geo-based login rules, if I come from the US I have to authenticate every 8 hours, but if I come from a UK address, it’s once a week.

So I set up an SFC connection to London, and send all the Microsoft type traffic (for Outlook, Sharepoint, Teams, etc) to London.

This works fine, my IP address appears to the authentication server as London, and I’m only asked to authenticate once a week.

However, when I do an upload to Sharepoint or other destinations, there is a hard upload speed limit at 1 Mb. As in, it is NEVER faster than that. If I drop the SFC connection and authenticate, I can get 6 to 11 MB. (I know, those aren’t great speeds either, but my Internet is very limited, and 6 to 10x is quite a difference for the larger files)

Why does the London SFC location have the hard upload speed limit?

What hardware are you using? What is your connection speed? What latency does your SFC connection have?

And how far away are you from London in km/miles?

Balance 20x, Starlink so it varies, 150ms-300ms, not quite 4000 miles.

However, if I remove SFC from the equation, the traffic still goes to London as that is where Microsoft is hosting the company’s office stuff, and I can get 6x the throughput. (6Mb vs 1Mb uploads) I can know the actual throughput speeds are accurate, based on the time it takes to upload a 2GB file.

Thanks for responding.

Latency hinders SpeedFusion throughput. The Balance 20X can do 100-150Mbps of SpeedFusion/SFC throughput when the latency is below 150ms. When it gets above 150ms it will negatively impact the overhead of SpeedFusion causing loss of throughput as well. This is sadly the case with any VPN technique.

For normal satellite internet there are TCP acceleration techniques that will hinder or enhance the SpeedFusion throughput, not sure if there are some settings in the SFC settings to get better performance from Starlink, as we don’t use Starlink with SFC ourselves.
