My nephew is crunching on his computer with half the computing power of mine but he is still able to get way higher results and points than any of my machines the only difference being my nephew has much faster internet speed.
----------------------------------------Does internet speed have any correlation to how fast you can finish projects? |

Internet speed is not a problem since one can queue up WUs. It's much more likely that your problem is with the PCIe bus speed or some other factor. Same projects? Need more details.

The better machine for crunching is:
----------------------------------------2012 Mac Pro, 3.2 GHz Quad core Intel Xeon 6 GB of RAM and the slower yet newer machine is: 2017 iMac 4.2 GHz Intel Core i7 4 core 32 GB of RAM The Mac Pro is outperforming the iMac. As a matter of fact it outperforms all of my iMacs. The projects are the same. ---------------------------------------- [Edit 3 times, last edit by Luvfishin at Nov 12, 2018 8:55:57 PM] |

Are you sure the 2017 iMac really has a i7 16 core? I would guess it is an i7-7700K with 4 cores/8 threads with 4.2 GHz. Should be the same number of cores as your Mac Pro with Xeon, but at a higher clock rate. So the iMac should outperform the Mac Pro I guess.
What you could check is the following: - is the CPU working at 100% utilization at any time? If not, there is either something wrong in the WCG preferences or the CPU is throttled due to thermal issues. - Do you get approximately (number of threads)*(1 day) per calendar day of run time on every machine? Check this under "My Contribution" -> "Device Statistics". If not, something is wrong |

You are correct about the iMac. It is 4.2 GHz with 4 core.
----------------------------------------All machines are set at 100%. It may well be a thermal issue. The iMacs get really hot in the fan goes really fast. I keep my house fairly warm as well and that may make a difference. The Mac Pro is not my house and I know that it is much cooler where it is. I have three different iMacs and they have all been running flawlessly since New. I will post the number of threads each machine does in my next post. I will also post my preferences for WCG. |

this is the Mac Pro:

Looks like the mac pro is averaging between 4-6 days of work per calendar day, and averaging in the mid 20k per day points.
The iMac is averaging 7-8 days of work per calendar day, and averaging mid 40-low 50k per day. Based on your specs of the mac pro being a quad with 3.2GHz, and the iMac being an i7 (8 threads) and 4.2GHz, I would say those numbers look pretty normal to me  |

Thank you for your input.
----------------------------------------Can you tell me why the iMac is producing less results although it is producing more points? |

That can be due to sub-project selection. Not all the sub-projects have work units the same length. They can vary quite a bit within the same project as well.

I can also confirm, that the output is approximately what I would expect.
Independent from that, what I would check on the iMac, is CPU temperature. I think I read somewhere that cooling for these is not the best and they run very hot when maxed out, especially with the i7. I would avoid temperatures above 80 °C, more than 90 °C is a no go. |
