Slow Internet even at off hours I want to run a VPN and it almost stops downloads! I thank that Via Sat should keep customers that already have service happy and not keep overloading with new account's. If I had other services I would.
Thanks Jerry

VPN's on a satellite internet can be an issue.  Some have good luck, others not, but it will slow your speeds even further.

With satellite internet, everything has to travel up to and down from the satellite.  That satellite is 22,350 miles above the equator.  When your computer is communicating with a website, the round trip time for a website to send a control signal to your computer and get it back again requires four 22,350 mile trips to and from that satellite.  At the speed of light, that translates to about 0.5 seconds.  Due to how the internet is structured, a website judges the speed of your internet connection as a whole by how long it takes for those control signals to go to and come back from your computer.

To counter this time lag problem, ViaSat has a proxy for your computer at the point where your internet service is connected to the internet.  That proxy acts on your behalf to negotiate those control signals with the website, and to receive the data from the website and then pass it on to your computer after compensating for that time lag.  The work that proxy does on behalf of your computer is called web acceleration.

Web acceleration gets rid of the problems that time lag would have caused for just about everything except for online games where constant real time interaction is demanded (e.g. first person shooter games) and VPNs where the data header is encrypted so the web acceleration is unable to process those data packets on behalf of your computer.

There are VPNs available that are SSL based, meaning that the data is encrypted but the data headers are available to be read and worked with by the web acceleration.  You might want to switch to one of those VPNs.  I suspect that the actual speed of your internet connection is not the problem here.

Last I knew SSL does encrypt headers however TLS requires that SNI not be encrypted. SNI (i.e. simple server name indication) has very little use for acceleration purposes. In fact one of the rationales behind Sparrow is to take encryption out of the equation at the browser level providing more flexibility in tweaking site performance.

It's also why secure sites load more slowly overall lacking the ability for deep packet inspection.

I could be wrong, it's been a while (about 3 years) since having to deal with all that hands-on and my memory is fading fast or perhaps standards have changed (in which case we can agree to disagree).

The question I have for the original poster is what's the speed like without a VPN and as noted the choice of VPN can make a difference (but you'll still take a bit of a hit).

This gives further information on what I stated above: https://www.bentley-walker.com/articles/101   Also, a good fraction of all websites (e.g. google and this forum) use https:// throughout the entire website.  That is SSL in use right there and there are obviously no problems with those websites over staellite internet.  I still recommend that the OP try one of those SSL based VPNs.

And again I think you might be reading a lttle bit into the OP's post - while he says he wants to use VPN and it almost stops downloading, let's first address his speed issues without VPN if any. I'm seeking clarification on his original post - if his speed is in the toilet without it, it's not going to get better with it. SSL has little to do with web acceleration, IMHO, and nothing in that article contradict what either you or I am saying. Obviously SSL works or we wouldn't be here, the question is whether VPN will regardless of its form/shape.

For all we know now, he may have one of the bad WiFi modems with s***hole performance; there's very little to go on here. Not really trying to arguie or debate you, trying to determine what the underlying problem is rather than a symptom. But yes an SSL VPN would be faster than a traditional VPN in some cases and it's a matter of trying the right one for the intended activity (not all are created equally).

Thanks for all your help I will check my speed and let you know . I have my desktop plugged in to the box I will check it there and by WiFi see if it is faster on the desktop.
