Will recompile and test. Yes, with pthreads it will not be able to use the special hardware support in the T3. > The SPARC T3 support up to 128 threads, so can I take the thread > count above 64? Or shall I just make the max thread count 64 by > default? 112 may be a good choice, but I do not know, you are the first to try this I think. If the T3 threads do not work faster for unbound, you may have to use the cpu count instead of the threadcount.
