I'm running Ubuntu 10.04 inside Virtual Box on a Window Vista 64 machine.
All the workunits are taking 12 hours on my machine, but the wingmen are returning theirs in about 2.6 hours. Boinc version is 6.10.17 and is set to use 100% of cpu time. Any ideas why it could be so slow on my machine? It's an i7 920 at standard clock rates with 6GB of memory. I set up virtual box to have 6 processors and gave it 3.6 GB of memory along with 50GB of disk space. System Monitor shows 6 cpus running in the upper 90% usage and memory usage as 1.5GB out of 3.6GB, so it looks like boinc is running and not using all the memory. In boinc there are 6 work units running and they do advance, just slowly. I'm a noob at both Virtual box and Ubuntu, so if you offer help you may have to provide detailed instructions on what to do.  I do know how to bring up a terminal window, edit a file, and run sudo, but that's about it.Thanks, Steve |

A Virtual Box of Ubuntu on Widows 7 - 64, with as I read it HT on. Maybe try to reduce it to 4 cores and also swap-off if it's interchanging allot with disk. For testing, switch HT off, if so inclined to find out for sure.
----------------------------------------And of course, is the CPU run on max? I've caught my Ubuntu LL quad a few times to drop the CPU while "on demand" to 1.6 Ghz even when BOINC was running full out, so switch it to The Max hz setting. Did you test any of the other sciences to see if any were running overlong too compared to wingman? Guesses for things to look at.

Thanks for the suggestions. I did switch to 3 cores and no HT. It didn't seem to make any difference. Watching the core temps I'm seeing what I would expect when running full out, so I don't think the cpu is slowing down.
I did initally run an HCC job and it did take longer than normal. I decided to not mess with this further and just wait until the Windows version comes out. Again thanks for the help. Steve |

----------------------------------------If you have an Asus board, try using the Asus Tools PC Probe II(should be on your MB CD/DVD, if not installed) as this will give give you a visual representation of the intensity and throughput of each core, plus temps etc etc etc. Chances are, you don't have an Asus MB!!!!

Cisf, yes I did. I didn't see any difference. Although that was after I installed boinc.
JSYKES, sorry I have an EVGA motherboard. Thanks everyone for your help, but I've decided to finish my goal of 5 yrs on HCC while waiting for Windows CEP2. So the cores won't be idle.  Steve |
