I know Delphi 2006 uses one of my IA32 move routines, but I had still expected some gains from using FastMove. Analysing all calls to system.move across a wide range of real-world applications provided the following interesting statistics. 2% of all Moves are of Zero Size 18% of all Moves are 1 Byte or Less 26% of all Moves are 2 Bytes or Less 40% of all Moves are 4 Bytes or Less 67% of all Moves are 8 Bytes or Less 90% of all Moves are 16 Bytes or Less 97% of all Moves are 32 Bytes or Less 1% of all Moves are Overlapping Moves (Source/Destination Overlap) Since the new RTL move routine is very efficient with moves of up to 32 bytes, and only 3% of all moves are of a size greater than this, using FastMove with Delphi 2006 will have very little impact on most applications. The benchmarking within the existing Fastcode Move B&V tool, although slightly weighted towards smaller moves, does not reflect these statistics. I therefore plan to modify the Move B&V tool to better match these real-world statistics. -- regards, John The Fastcode Project: http://www.fastcodeproject.org/ Back to top Pierre le Riche Guest Posted: Fri Mar 10, 2006 8:03 pm    Post subject: Re: FastMove and Fastcode Move B&V Tool Hi John, Quote: I have recently been looking into why FastMove makes so little difference with Delphi 2006 applications.

I had overlooked that. -- regards, John The Fastcode Project: http://www.fastcodeproject.org/ Back to top Dennis Guest Posted: Tue Mar 14, 2006 1:03 pm    Post subject: Re: FastMove and Fastcode Move B&V Tool Hi John Go ahead ;-) This B&V is quite old and needs some updates. You proposed a new subbenchmark. Report failures as validation pass/fail not as exceptions. Observe that our B&V + scoring system worked well because your new tests confirms that the new RTL Move is very hard to beat. I do not think that we have to change subbenchmark weigths very much, because our functions are highly optimized and a winner is not likely to be slow in subbenchmark4 (small moves). Subbench4 carries alot of weight as is and I do not think we should increase it to much more. The other subbenches are also important, but I agree that they are much less important than small moves as your statistics show. I do not have an exact suggestion for subbench weigths, but increasing the subbench weigth by 50% is probably ok.
