Hi Everyone,

I am using Boost Threads (1.38) as threading library and I also use  
the thread_specific_ptr to store a minor amount of data per thread (I  
think currently it is like 5 different pointer values per thread).  
Technically everything works out fine, but I am having a performance  
problem on Mac OS X. On Linux the performance is 10 times faster than  
on Mac OS. If I use pthreads on Mac OS I have identical performance to  
the Linux version. Both versions are running on the same machine using  
8 threads both.

Is there any known problem with shared pointers on Mac OS? I have  
tried different versions of boost, compiled it myself and also used  
macports - every time same results on Mac OS. Any hit or possible  
workaround is very welcome :)

Thanks and regards,

Oliver
