I was wondering whether I should get another dedicated server for Traces of Illumination with a single-core or multi-core processor. According to my tests so far, and e.g. http://forum.unity3d.com/viewtopic.php?t=12184 Unity doesn't really make use of multiple cores, so my feeling would be that a fast single-core system would be a better server-hardware platform for a Unity game server than a slower multicore system. I'm comparing, for instance an Intel Pentium 4 2.6 GHz with an Intel Core2Duo 2 x 1.8 Ghz. The nice thing about the Intel Pentium 4 would be that it's also about 30% cheaper (so I could get more machines when there's more players). And, I would think that it would be quite a bit faster (as there's no rendering on a game-server, I'd assume that processor speed is the most significant variable; aside of networking, of course ;-) ). The OS would be Windows, and there would be no other services running on the machine. Any insights on this?
