• rob111rob ifstream performance

  I'm finding that using ifstream to read in numbers from a text file runs slow in MFC applications (vc++ 6.0). This seems to be related to MFC applications being multi-threaded. In a console application without MFC, the following code ifstream in("test.txt"); double x; while(!in.eof()) { in >> x; } in.close(); runs 3-4 times slower when Project Settings - Code Generation "use run-time library" is Multi-thr ...Show All

  Hi, Could someone clarify which Visual Studio 2005 edition is required in order to have the ability to profile C++ code execution.
