(moderation:
I have just had an einstein task that ran 15 hours. I received 390 points after crunching the task. Is this the typical no. of points for crunching a task for 15 hours?(With a Mac with i7 processor)

The task was a S6 CasA task and these are worth about 390 points so that seems correct.
As to the runtime my i7 3770K @ 4.1GHz with HT=on runs them in about 7-8 hours with some taking a bit more, but not 15 hours. It's not the same CPU but I don't think there all that different. Someone please correct me if that's wrong!
Do you run anything else CPU intensive on the computer that might compete with Boinc?
Do you monitor the CPU temperature so that it's not overheating and downclocking to protect itself?
Yes I would check the CPU

Yes I would check the CPU temp since an older slower CPU did that same task quite a bit faster.

From what I can see everything looks fine. The total crunching time really was more than 14 hours but the CPU time is less than 10 hours. So it appears that your computer was just busy with other things during this task.

LOL, slower and older CPU.
That CPU that you see there is the Xeon E7 with 4 CPUs, all with 10 cores, thus a 40 core CPU system.
This Xeon is based on Ivy Bridge technology.
Thank all of you for your

Thank all of you for your responses. I had not thought of checking the Temp. I will monitor that and see if there is over heating.
A more direct approach than

A more direct approach than monitoring temperature would be to check the actual CPU clock speed while crunching. There are numerous tools for this in Win, but I don't now Macs.
My 3770K (pretty much the same CPU) at 4.1 GHz does them in 23 ks, which is quite a bit faster than your 35 ks, even accounting for the difference in CPU time and elapsed time and clock speed (your should run at 3.5 GHz while loaded on all cores).
And in Win it says "1.05 SSE2" in the application description, whereas it just says "1.05" for you. If the Mac binary wouldn't use SSE2 (the CPU has, of course) that could cause a significant peformance hit. But it could also be that all Mac apps use SSE2, so there'd be no need to specify it. Don't know.

Yeah I was just making a quick stop in the middle of doing several other things so I just saw the "2.80GHz" when I was looking and his is a i7-3770 CPU @ 3.40GHz 8 core.
I see it does say 40 processors now but it doesn't mention Xeon there.
