Well, we've just discovered that the most important part (for performance) of SKAS3 *is* supported (instead of "mode=skas0"/"skas0" pass simply "noprocmm", the UML will run happily). I don't have data about the performance loss, but I think on this side it'd be not big. However, the SYSEMU code isn't implemented for x86_64. And that is a bigger problem indeed for performance. Look at the end of http://sysemu.sourceforge.net/ But ignore the "60%" number since it's a micro-benchmark (i.e. unlikely to represent a real application). The 33% one is more realistic. > I am asking this > because due to the fact the server is running at a remote location, > having someone installing me another host os would be costly. -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
