Linux as of at least 2.4 kernal suports user mode and kernal mode threads. No 
idea how the Perl implementation maps 

Multiprocessor systems with chip multithreading are the norm Intel Core2 Duo 
for example, much less the sun SPARC which has gone from 2 cpus each in a 
socket to massive multithreading. The coolthreads goes now to 128 hw threads of 
execution 8 per core 2 sockets and they also have 6way regular UltraSPARC. So 
on the newest Mseries you could get 256. That would be one expensive platform. 
SPARC isn't cheap but 5240s are in the $30k range a 8board domain on an Mseries 
is probably $600k. 
But there are firms using them. My employer has a pile of 5240s and they do run 
Perl on them along with Oracle or Informix (we have both in the shop)

So the performance on Linux should be slowed down in order to deliver 
the same experience as on VMS?  For which "target audience" is that 
true?
