There is no Solaris 2.9. Assuming you mean Solaris 9, yes, the default threading library has been improved.

See my comment in my reply to your other post. Find out where your bottleneck is before rushing in to change things. Get yourself a copy of Solaris Performance Tuning by Adrian Cockcroft and Rich Petit, and read it from cover to cover. Get a copy of Brian Wong's Configuration and Capacity Planning for Solaris Servers.

Yes, I think you can apply some patch or something that'll improve the Solaris 8 threads, but I can't recall the specifics.
