With CS Source, Windows servers have always performed better than Linux ones. Windows server can have server slots than Linux since CPU usage is lower and tickrate more stable - for some reason. Hard to do good port to Linux or its stiched in with iron wire, bubblegum and glue? Same thing is with OB engine. If SSE2 is disabled, its propably for a reason but i doubt you, me or anyone else will get any kind of direct reply from Valve in matters that fall into commercial secrets and their Source engine is one of them. I doubt they will talk about how it works - in full detail. Funny thing is that most servers that run Source engine are on Linux - not Windows.
