over the weekend the question of scalability was raised on the linux
kernel mailing list and people are shipping 1024 cpu systems with linux,
and testing 4096 cpu systems. there are occasionally still bottlenecks
that limit scalability, butunless you run into a bad driver or filesystem
you should have no problems in the 8-16 core range.
any comparison between Linux and any other OS needs to include a date for
when the comparison was made, Linux is changing at a frightning pace (I
think I saw something within the last few weeks that said that the rate of
change for the kernel has averaged around 9000 lines of code per day over
the last couple of years) you need to re-check comparisons every year or
two or you end up working with obsolete data.
