Looks that new code is a little bit faster though the recursive spinlocks introduce some small but noticeable speed overhead. Probably due to cost of _hb_gettid(). Maybe we will find some workaround for it in the future. Now it's important that it works. BTW it looks that your system is not configured to use 2CPUs and everything is executed using only one. Do you used SMP OS2 release? If not then scalar factor will always be close to 1. best regards, Przemek _______________________________________________ Harbour mailing list (attachment size limit: 40KB) Harbour@harbour-project.org http://lists.harbour-project.org/mailman/listinfo/harbour
