Why does changing `const ull` to `const ull&` in function parameter result in performance gain? http://stackoverflow.com/questions/14805641/why-does-changing-const-ull-to-const-ull-in-function-parameter-result-in-pe that stalled or missed in the cache or there was a mis predicted branch etc. So when you see a big count look back to see what.. the processor is stalled due to a cache miss or a mis predicted branch or some internal data dependency. I increased the number..
What tools do you use to develop C++ applications on Linux? [closed] http://stackoverflow.com/questions/17228/what-tools-do-you-use-to-develop-c-applications-on-linux __builtin_prefetch. I tried to use it to find hot mis predicted branches as well but couldn't get that to work for me. share..
Portable branch prediction hints http://stackoverflow.com/questions/3702903/portable-branch-prediction-hints canonical way to do static branch prediction is that if is predicted not branched i.e. every if clause is executed not else and loops..

Can a local variable's memory be accessed outside its scope? http://stackoverflow.com/questions/6441218/can-a-local-variables-memory-be-accessed-outside-its-scope associated with some program variable cannot be easily predicted ahead of time. The compiler generates calls into a heap manager..
What is the performance cost of having a virtual method in a C++ class? http://stackoverflow.com/questions/667634/what-is-the-performance-cost-of-having-a-virtual-method-in-a-c-class cycle but that the indirect jump usually cannot be branch predicted. This can cause a large pipeline bubble as the processor cannot..
What are the common causes for high CPU usage? http://stackoverflow.com/questions/9275262/what-are-the-common-causes-for-high-cpu-usage idea is that a thread with a lot to do doesn't need to be predicted as compute heavy it will just always be available whenever something..
