Re: A question about multi threading.
That's why using 8 threads is only slightly faster than using 4 - and not approaching 8 times faster than single. The extra performance of 8 over 4 comes from the 4 'hyper cpus'. As the threads are cpu-intensive, you don't get 8 times the performance as the 4 hyper-cpus are not 'real cpus'.
All advice is offered in good faith only. All my code is tested (unless stated explicitly otherwise) with the latest version of Microsoft Visual Studio (using the supported features of the latest standard) and is offered as examples only - not as production quality. I cannot offer advice regarding any other c/c++ compiler/IDE or incompatibilities with VS.
