I suspect that the procedure initialization time is added to the first
explicit statement. The initialization can include try-except/finally
blocks, memory allocation (in constructors) or more.

Please create another procedure or method, that uses FillChar not as the
first statement, and test again.

I am not sure what you are asking. The callgrind outputs the call tree and other information....

It's not the first time that somebody complains about slow FillChar. I simply doubt that it really as slow as reported. In above table I'd expect that SysGetMem should be slower than FillChar.
