There isn’t much to tell here as this has been mentioned a lot of times in many other articles. The basic and major differences between these two are the price and number of users. Linux is the cheaper version as it is free giving it a great advantage compared to Windows as its price can go very high, depending on the package you decide yourself for. However, this fact is even if it is still so obvious that Linux is cheaper, Windows prevails over Linux in many ways, starting on the supporting technologies, which are the key in configuration of the game server, but also the number of Windows user will always be larger and therefore the server must be Windows too.
This is only a part of all of the things that need to be completed and conditions fulfilled to produce the most efficient way, that will provide all what it takes for a game to function in the multiplayer mode. Internet connection, server resources, own computer configuration, the quality of multiplayer mode, they all have to be maxed out as much as possible for best performance. The number of factors at play here are enormous, but still there are people who take care of them all and therefore as a result the game that they play, online, is worth all that effort which must be put in it.
