Jim,
At risk of seeming a bit disagreeable, I would think that porting an OS in
1994/5 to Intel chips of that vintage has little or no relevance to
optimizing X86 code 12 years hence. What I am saying is that the numerous
profound changes to hyperthreading, multicore platforms, and the instruction
sets of SSE, SSE2, MMX, and all the other changes to the Intel family in the
ensuing 10 years time has rendered their optimizing skills as being of
little or no modern value.
More to the point, the applications like Final Cut really need to optimize
performance of both the application code and the processor / OS workload so
the really essential and modern skills sets in Microsoft .Net framework,
Microsoft Visual Studio, etc. would be entirely lacking from a 1994/5 person
porting an OS like NextStep from a Motorola environment to the Windows
environment of that 1995 era.
