Thank you Jim, interesting figures. I may be due to Win7 better memory management. Have you been considering Linux? You are welcome. Yes, I have looked at Linux, as noted above. The work units were not as consistent there, but my conclusion is that Win7 64-bit is as good as Linux 64-bit, though beyond that I don't think you can say. For my desktop, I need Win7 anyway, so will just find work that suits it. Fortunately, that includes MCM. Maybe I will try Linux again later on one of the dedicated machines, but WinXP is much easier for me to manage, and does well on the GPU project (GPUGrid) that I am also running under BOINC.

I checked the Win7 machine, and it is running at 3.7 GHz, but don't have a way to check the Linux PC. However, it is running in the default "Ondemand" mode, so it should be about the same. Assuming all the appropriate modules are loaded, including the stats module, cpufreq-info should tell you exactly what proportion of the time each core has been at what speed. Alternatively, as a quick way to get current speeds, "grep MHz /proc/cpuinfo" |

Alternatively, as a quick way to get current speeds, "grep MHz /proc/cpuinfo" Thanks, but I have now converted that machine to WinXP, and found that it was in fact running at 3.7 GHz, so I expect that it was the same under Linux since everything was at default. (I hope to check out Linux x64 again when Ubuntu 14 comes out, but for now XP is doing what it needs to do.) |

You might want to try Linux Mint instead of Ubuntu since it probably uses far fewer resources for the "cosmetic" part. I don't have any numbers but from what I have noticed Linux X64 seems to be somewhat faster with MCM.
----------------------------------------I just installed Linux Mint 16 x64 and it has now finished 4 tasks and I noticed that when I had my Phenom II X3 2.8 GHZ, Mint also finished tasks faster than W7 x64. I don't have any tasks from same/close batches but here are some results from W7 x64: MCM1_ 0002978_ 7593_ 2-- PC Pending Verification 15-03-2014 18:03:15 16-03-2014 12:06:40 5.92 / 6.54 78.6 / 0.0 MCM1_ 0002971_ 5674_ 1-- PC Valid 15-03-2014 13:31:52 16-03-2014 09:55:00 5.01 / 5.55 66.2 / 84.7 MCM1_ 0002971_ 2150_ 0-- PC Valid 15-03-2014 13:28:44 16-03-2014 09:55:00 5.04 / 5.66 67.5 / 66.9 MCM1_ 0002970_ 6075_ 0-- PC Pending Validation 15-03-2014 13:23:37 15-03-2014 22:55:17 5.00 / 5.59 70.1 / 0.0 MCM1_ 0002955_ 0608_ 1-- PC Valid 14-03-2014 22:04:19 15-03-2014 19:20:59 3.39 / 3.87 49.4 / 49.5 MCM1_ 0002752_ 6243_ 2-- PC Valid 14-03-2014 15:07:22 15-03-2014 17:56:53 5.96 / 8.56 104.0 / 113.7 Linux X64: MCM1_ 0003061_ 7909_ 2-- Mint Pending Validation 16-03-2014 13:47:38 16-03-2014 18:32:56 4.22 / 4.52 108.2 / 0.0 MCM1_ 0003061_ 0853_ 0-- Mint Pending Validation 16-03-2014 13:45:33 16-03-2014 17:37:54 3.42 / 3.67 88.0 / 0.0 MCM1_ 0003061_ 7921_ 2-- Mint Pending Validation 16-03-2014 13:47:38 16-03-2014 16:56:19 2.84 / 3.03 73.2 / 0.0 MCM1_ 0003061_ 7899_ 2-- Mint Pending Validation 16-03-2014 13:47:38 16-03-2014 18:32:56 4.12 / 4.41 105.6 / 0.0 Batches are just too different for a comparison but I am going be using Mint for a while now. However due to that, the fact that Linux seems has lower runtimes is useless for comparison sake. Two more tasks are at 41% and 45% with 50 minutes CPU time and 1 hour and 30 minutes CPU. The computer is running an A8-6500 at 3.5 GHZ.

I don't have any numbers but from what I have noticed Linux X64 seems to be somewhat faster with MCM. I used Mint for my comparison noted above, but had problems remoting into it from Windows 7 64-bit; the VNC server crashed it, apparently a known problem with that release. I think Ubuntu does not have that problem. It is said that Mint is based on Ubuntu, and just adds more GUI stuff and applications. Therefore, Ubuntu should be as fast, but I will defer to the Linux gurus for that one. |

I have been successful in using Teamviewer to remote into my Linux Mint machines from both of my Windows machines, one Win 7 and the other Vista. I have used vnc in the past with all Windows OS's, but have not tried it on Linux. Teamviewer is free for personal use and was way easier to set up than vnc was. Cheers

Of course, you can just install cinnamon in Ubuntu and get the same result. When I used Ubuntu, RAM usage would generally be in the the 1.7-1.9 GB out of 4 GB, just sitting there with 2 WCG tasks running. With Mint, 2.7 GB of RAM, 4 WCG tasks running and 1 Wuprop, plus music player and browser running, it doesn't even reach 1GB.
