My desktop dual boots windows and linux. Processor is an old AMD 6300 fx CPU.
Rrecent SCC tasks take 1.4-1.6 hours to complete on windows. For example, task SCC1_ 0002762_ Lin-ZNF-F_ 5402_ 0-- took 1.44 hrs. But the same machine running linux completes SCC tasks in 0.85-1.10 hrs; e.g SCC1_ 0002819_ Lin-ZNF-F_ 27826_ 0-- took 1.01 hrs. To my eye, the tasks look identical. Anyone else notice something like this, or have theories as to why this happens? |

That what others have experienced before you.
On Zika, SCC and Ebola Linux is much faster than Windows. On the other projects there is no or small difference between linux and windows. So if you can I would suggest to run WCG on Linux. You will get more points and the work of the project is done faster. |

Shhh, its a secret! ;)
Does anyone know where macOS would fall in this area? Would macOS also be Linux in the crunching times, or Windows? Any thoughts? |

Do you know what it is about Linux that makes these specific projects crunch faster? Is there some sort of math that Linux supports that Windows does not? |

I think the reason 64-bit Linux is much faster in the VINA sciences compared to 64-bit Windows has to do with much better memory management on Linux and compiler differences. At least that's what I seem to recall.

I ended up installing Ubuntu under VirtualBox on all Windows machines and running WCG there now. The gain is significant (30-50% improvement on SCC1) even with all the VM overhead.

Since macOS is a(n) Unix clone, guess where it stands  It is close-or-on-par with Linux. Cheers and NI!  Crunching@Home since January 13 2000. Shrubbing@Home since January 5 2006  |

I wonder if there's anyone who tried to execute boinc tasks from the same platform and with different environment?
For example: On a amd64 platform windows linux windows-docker linux-docker windows-linux vm linux-windows vm |

Since macOS is a(n) Unix clone, guess where it stands It is close-or-on-par with Linux. Cheers and NI! But a low end 2 core/thread Celeron notebook with 2GB of RAM, running Windows 10 finishes on general SCC jobs in about 80% of the time that they take on a 2 core/thread Core 2, 3GB of RAM under Linux Mint 19. And my 4core/8 thread i7 (8GB RAM) MacBook Pro running macOS 10.13.6 (High Sierra) is in general about 10-15% slower than an equally speced i7 Dell Optiplex running Windows 7 Pro or Windows 10 Pro... There is a big differences on the runtime of various batches of SCC WUs, on this i3 (4 threads, 8GB RAM) running Windows 8.1, the runtime fluctuates between 50min to 4 hours...  |
