Hi there,

I currently bought a PC with an i7-6cores(windows8) to run matlab (simulations) but I found it runs my application very much slower than my old laptop with Intel Core2. I understand that one way to speed the execution would be using special coding (parfor, ...) but I think there is another problem that I can not identify.

Is there a similar problem as the one I just described? Is there a possible fix for that?

Thank you very for any help you can provide me.

Juan

Jan, I am sorry. I made a mistake repeating part of the info in the third and fourth line

Hi. The memory in each computer is obviously important factor. The hard disk access speed if very important, so is MATLAB installed in the same disk where the code is saved or separate hard disk? Finally, there is always an overhead time when using multiple cores which will lengthen time if code is not really a complicated one (e.g. serial tasks rather than parallel). Regards
