Hello, If you take a look at the graph of the benchmarks that i did on my parallelsort library , you will notice that i am getting a superlinear speed up , look at this: http://pages.videotron.com/aminer/parallelsort/parallelsort.htm So a question follows: How am i getting this superlinear speed up on this example using 10 millions of strings? My answer: Cause when you are using mutliple threads and mutiple cores, my parallelsort library is maximizing BETTER the locality , that means the caches are used more efficiently when more threads and more cores are used . You can download my parallelsort library from: http://pages.videotron.com/aminer/ Thank you. Amine Moulay Ramdane
