OK.. done.. Made one minor fix to the implementations for an extra argument to decrement count (checked into CVS). The results for the timing test are:
With BOOST_SP_DISABLE_THREADS..
* cw-8.3 debug, 18.06 * gcc-3.3 debug, 50.98 * gcc-3.3 release, 18.47
Without BOOST_SP_DISABLE_THREADS..
* cw-8.3 debug, 21.08 * gcc-3.3 debug, 51.07 * gcc-3.3 release, 18.52
I didn't build the release of cw-8.3 because it was taking along time, more than 10 minutes, to compile some of the files. It's most likely one of the unbounded optimizations CW likes getting into.
To me the curious aspect is that CW is faster in debug mode than GCC in release mode. It's nice to see the threaded code be almost as fast as the non-threaded code.
Great. ;-) Well-designed uniprocessor systems "should" be as fast in threaded mode; we'll probably see a bigger hit on a dual PPC. We can officially uncomment the #ifs in sp_counted_base.hpp now, I guess.
