Not in my experience, although libsunperf helps a lot
Thank you very much, Profs. Ripley and Peng! It corrected a big
misconception in my mind.
By the way, does the Sun Forte 7 compiler produce faster R than the GCC
3.4.1 compiler (which we use)?

Are you using an optimized BLAS for both builds? That's one possibility. Also,
64-bit builds use up more memory initially since the pointers are bigger. I've
tried both 64-bit and 32-bit builds on Sparc/Solaris and haven't seen any slowdown.

Hello, everyone! I guess no one is still using R on Sun Sparc these
days. But our department has a (pretty new) two-CPU Sun server. We
recently compiled R as a 64 bit application and expected a performance
boost. But it runs 25-30% slower than the 32 bit version of R. Anyone
knows why this is so? T
