thanks.  if you don't mind I have some miscellaneous questions:

1. these inefficiences aren't such that it will keep me from using 4.5 SMP
for production environments, are they ?

2. is 5.0 SMP slated to do 8 processors (or more?)

3. do you know how many processors sparc64 FreeBSD SMP supports ?  Or will
it always be the same number of procs that x86 supports ?

thanks!
