However, this still means that when the matchmaker determines that more servers are needed, it still needs to start new server instances. In our testing, this startup time can take anywhere from 3~7s, regardless of the size of the AWS server we use or code optimization. This is purely the startup time needed for loading the code up from EBS. (we tested this using Unity-based servers) In today's multiplayer game, it is crucial that we get players into the game asap, and these additional seconds could mean losing a player.
Consequently, we are asking that there be a way to have Playfab also spin up spare server instances. This means we can further reduce player connection time into the game. players
