Minecraft (and Java) just runs great on Linux. I've personally experienced a 30% performance improvement from Windows.
I once tested the MS-Windows version on Wine on Linux vs MS-Windows on the same box. Both wine and native were faster on Linux, with the native Java version being the fastest (but not by much).
