Build Tester v.126.96.36.199:
This is a marvellous tool to measure the speed of your chess program.
Just insert all the engines executables you want to test with "Update Engines to Test List" and click on "Begin Tests".
I advice to leave all the settings to default although you can make an exception for the threads: in the Command Line box you can set them as second parameter (the value 1 in the picture between 16 and 15). While the standard test uses only 1 thread you can test the engines on more of them to see if they make a different performance.
Build Tester works only on Windows platforms, no Linux, no Android or MacOS.
Inside the zip archive you will find an exhaustive pdf guide explaining all the details of this program.
