Open Task Manager while Prime95 is running and see how much of the CPU it's using. If you're running one thread of work, it should be 50% (or close), or with two threads of work, 99%.
Did you let the benchmark also run with using 2 threads? Are the results of that closer to the average?
Are you sure that Prime95 is detecting your CPU type and speed correctly?
Especially if this is a laptop, are you having overheating/throttling problems?

Another possibility is sub standard memory. Try to use CPU-Z found at www.cpuid.com to check your effective memory and CPU speed.

This computer is a laptop, its actually a MacBoook. since i started running prime95 my computer has continuously left the cooler on.I think this is normal but i dont know.So since its a mac i dont have task manager and i dont know if it has something similar to it.So if you can help me with a Mac op it would be great.

You already made a thread. http://www.mersenneforum.org/showthread.php?t=12297 Why did you remake it?

victorvicentim,

Just because you've now registered is no reason to "spam" this forum by uselessly posting a duplicate of what you already posted before you were registered.

We can all see your previous thread and don't need you to waste our time by starting an identical one.

- - -

Moderators,

Please change this thread's title to something like "useless duplicate of another thread" -- if you're going to let it survive at all, that is.

Bring up a terminal window and type "top".

Alternatively, run the Activity Monitor application.

Mac's Activity Monitor is different than Windows Task Manager.

Your machine is a dual-core. The percentages in Activity Monitor will add up to 200%. Since prime95 is getting 150% some other processes are getting 50%. If you can reduce the amount of time these other tasks take, prime95 will get a faster. When I'm not using my Mac, I put VMWare and FireFox to sleep as these two are rather piggish.
