I've changed the problematic phone over to using only 4 cores now and sure enough - the runtime is half or less, and the CPU time compared to runtime is 98%+ efficient now! Still find it odd that another, identical, phone doesn't have this issue though - on my recently bought one (the one on 4 cores now), the runtime is at about 17-20 hours with about 98-99% efficiency) and the other P9 lite is still sat on 8 cores, yet has a runtime of about 25 hours and about 95% efficiency.
----------------------------------------Would anyone know why the 4/4core setup of the phone caused an issue in terms of runtime/efficiency on one, but not on the other? Cheers, Chris    |

A related problem, possibly. I needed to download some old stuff from a retired AMD Athlon 2 core 3800+, so I thought I would run opn on it while it was connected. I am getting elapsed times double my CPU times. Task Manager is never showing more than 49% for either of the units running. Sometimes it is 0/40+ and occasionally it is say 23/25 or thereabouts. Nothing else is currently running on the machine. It is running Vista SP2 with 3 GB RAM. I am only keeping it in reserve normally in case my main machine breaks down so that I can run my Bank program which uses MS DOS. Mike Would it be possible that your system doesn't have enough physical RAM? It might be swapping a lot and therefore bottleneck the CPU? |

That could be it. Anyone know how much RAM is needed for OPN, please?

That could be it. Anyone know how much RAM is needed for OPN, please? According to system requirements , it's just 250MB RAM, like SCC. But with 8 WUs running at the same time, it needs a lot, I guess.
