I have a basic question if I have executable files on two computers with the same CPU speed (Release, Visual Studio 2010 ) I run two separate Windows operating systems, i.e. Windws7 versus XP, would I expect to see different CPU usagees when I measure it using Task Manager? CPU speed is the only factor in measuring CPU usage?
Thank you.
Sir
Is there a separate OS? Yes.
Operating systems are between the programs that you are running and the bare metal that they run in. Change the OS and remove the facilities that naturally develop and consume resources - these are Things that move in the background; Or they may change the way in which the OS speaks on the hardware.
In addition to this, the measurement of CPU usage is done by the OS. The chips do not have a tachometer running on "87% red lines", but rather that "tech" is made largely by the OS.
After understanding your situation better: I will give you a look at the performance monitor () which ships with both XP and Win 7, and you will get the level of processor usage Provides much better-grain extension in Another (very good) option will be to consider a profiler on your app to run on both OSes and compare results. This is likely to be the best option for benchmarking your app on both OSes.
