why do I got such a low score when i use bench function in matlab2024a

when I was using MATLAB 2024A, it often got stuck, and then became normal after a few seconds . this was very different from my previous experience, and I feel my progam runs very slowly. So I ran the bench function and found that the score was terrible, and I don't understand why this is happending ......

In each MATLAB release, the bench() function compares your computer against some of the newest computers on the market at the time. So the ranking of your computer would natually fall comparing to the ranking you got in earlier MATLAB release.

thanks. My laptop uses the latest cpu ultra9 185h and I'm wondering if matlab2024a is not using the correct Pcore,or using AI core? The main reason is that when I use matlab2024a, the same program runs slower than my laptop three years ago. So I used the bench function to test. The results disappointed me.

@cui xy

MATLAB is definitely not using the AI core.

Are there any other reasons why the program might run so much slower than in previous version of matlab...

[Fangjun Jiang]

It could be some "optimization gone wrong". We've had such cases and the Mathworks acknowledged and explained the reason and was later improved. Send your code/program to tech support for analysis. Or you can do profiler yourself first and find out what part was making the difference. Make a simple example of that part and send to the Mathworks.

Hi Cui, if you can find another computer with similar hardware config and higher bench score, we can say there is issue in your computer settings or drive. Otherwise, it is not easy to narrow the issue by bench results.

Besides bench, you can check some other settings, like

1.power settings, some latop will limit performance without plug-in

2.is MATLAB installed on SSD?

3.is other software using too much system resources? e.g. security, update

PS, if you are using GPU, gpubench would help, rather than bench.

Do check your computer's power settings, to make sure they are set to "best performance".

I used best performance and ssd. Thank you for your reply. If we can confirm that it is not the problem of the new CPU ultra9，such as Pcore,Ecore,AI cocor，core Scheduling.then I will try to find the problem. thank you
