Hi Roland

As far as I know you are the first reporting that. No such problem here.
Let me think... Looks like hardware issue to me.

What is your hardware ? Did you made any change recently ? Did you check
you CPU temperature ? If you have CPU cooling problem on an Intel it won't
burn but the performances would decrease drasticly. Have you noticed any
performance decrease on other programs like games ?

I might be completely off the track but this is my first thought.

Marc

EDIT;;;

Run the Boinc benchmarks and compare to the rusults you had before.

Just like in SETI@Home Classic, the time to process one work unit is not constant across all work units. One of the influences is the "True Angle Range" with some units causing longer processing times. In addition, the content of the work unit may have a lot of noise, spikes, Gaussians, etc. and this will also increase the processing times.

I would have to agree with Petit Soleil, i've never heard/had that kind of issue before.

yeah...but a 9 hour difference? It seems to me that it's happening across quite a few WU's.

perhaps one of those processor integrity tests wouldn't go amiss here.
