On an "old" mobile cpu (Intel T4400, with 2200 Whetstone and 4270 Dhrystone) wus duration is 1800 secs. With other cpu (Amd FX-6300, with 2850 Whetstone and 10500 Dhrystone) wus are 2800 secs. Both are Win7. Is it normal? |

Hi! Could you give us more information about those tasks? With that data we think that it can be possible, but if you send us more data of those specific WUs we will give you a more specific answer. Thanks for you attention, Joel. |

a bit dated but still valid.... I know that FX-6300 is not a high-end-cpu (like Xeon), but this is the only project (both crunch Rosetta, Poem, Tn-Grid, ecc) in which is slower than mobile cpu (that is used at 60%, cause heat). |
