Ok.. Did some tests on my mbp (CD 2Ghz, 2GB ram, 90% cpu limit, one task per core).
On each result I indicate the time for one core to calculate one WU.
As the processor has two cores, of course the score of the processor is twice faster (two WU calculated at the same time).

On Os X 10.4.1 : about 13mn30s for a WU.
On XP SP2 via BootCamp : about 10mn20s for a WU.
On W2000proSP4 via Parallels Virtual Machine : about 11mn for a WU.

As you can see, the OS X client is not enough optimized. It's obvious, as running BOINC through Parallels 3.0 (Windows 2000 on MacOs X virtualization), is faster than Os X alone ! :)

(13mn40s for mbp, 14mn for the iMac).


Hmm, both of those times seem very long for those types of processor. Have you tested either of them on Windows with bootcamp?

Not done, but I'll do it as soon as possible ! ;)

Hi,

No errors here.
- 1 Macbook pro Core duo 2Ghz, 2GB ram, Os X 10.4.11.
- 1 iMac Core 2 duo 2.16Ghz, 1GB ram, Os X 10.5.2.

Speed increased but not much compared to PPCs.
The mbp is 5 seconds faster than before on a WU.
The iMac is 15 secondes faster than before on a WU.

But it's still strange. The iMac should be faster than the mbp, and is not ! (13mn40s for mbp, 14mn for the iMac).
