On a CPU-intensive application, the 64 bit exe runs 40% slower than its 32 bit counterpart. It's a C++ app with a workload typical of a compiler.
Are there known slow spots on the 64 bit runtimes? I'm using latest gcc/runtime as shipped by MSYS2. Tried to profile the executables but gprof doesn't output any numbers, just the boilerplate. (Yes, I'm passing -pg to the g++ instance that invokes the linker.) ------------------------------------------------------------------------------ Slashdot TV. Video for Nerds.
