Here is what I use for sampling profiler:

(On Windows)

Build with LDC, x86_64, with dub -b release-debug in order to 
have debug info.
Run your program into:
- Intel Amplifier (free with System Studio)
- AMD CodeXL (more lightweight, and very good)
- Very Sleepy

(On Mac)

Build with dub -b release-debug
Run your program with Instruments.app which you can find in your 
Xcode.app

(On Linux)
I don't know.


Though most of the time to validate the optimization a comparison 
program that runs two siilar programs and computer the speed 
difference can be needed.
