Jeff,

I think your info about context switching time is out of date.  Here's 
some sample PIWG data for our ActivAda Realtime product, an Ada 83 
compiler for 32 bit Intel x86 processors.  The benchmarks were run with 
checks on and optimizations on.  The target is a 75MHz 80486 DX4.

But like another person said, it's mostly a matter of processor speed, 
and this is certainly not the fastest thing we or others have.  The real 
issue is predictability.
