Yeah, SunOS 4.1.4 had some MP work done to it. Pretty sure I posted
about it here and dragged Greg Limes into it. He was involved in that
work. I think it sort of worked up to 4 CPUs but as with all early
kernel threading stuff it worked better when it was a 4 cpus of
userland work, less so when it was 4 cpus of I/O.
Side note: I was one of those people who was pulled
kicking-and-screaming
into the Solaris (SVR4) world
You and me both.
