I have a question regarding performance issue I am seeing on multicore Windows systems. I am creating many threads to do parallel tasks, and on multicore Windows systems the performance is abysmal. If I use task manager to set the processor affinity to a single CPU, the program runs as I would expect. Without that, it takes about 10 times as long to complete.
Am I doing something wrong? I have tried DMD 2.0.37 and DMD 1.0.53 with the same results, running the binary on both a dual-core P4 and a newer Core2 duo. Any help is greatly appreciated!
