So, there are lots of Jit.si servers out there. If I choose to pay for a premium server, like 8x8, what is that going to get me, above and beyond the free servers? If I’m selecting between the free servers, what should I be looking for? I see that jitsimeter reports speed, response, privacy, etc. I would think that lowere response times and higher speed would be the best, but won’t that be affected by my location? Is jitsimeter testing from my location? I’m in the USA, and many of the servers listed (including meet.jit.si) have X in the speed and response time columns. What does that mean?
