8 hours, Sek - 20:24 is a time, not a duration. :-p

Still, that's about 0.3 efficiency - and 40 hours is an awfully long time for a work unit.

It says:

- <time_stats>
<on_frac>0.990634</on_frac>
<connected_frac>-1.000000</connected_frac>
<active_frac>0.999596</active_frac>
<cpu_efficiency>0.457296</cpu_efficiency>
<last_update>1190590069.265625</last_update>
</time_stats>

I see that the efficiency is smaller that it should probably be, but why? Although after setting the CPU using to max 100% it seems to speed up a little - started at noon and now 85,6% done - in thirteen and a half hour, that is much faster than previous units. Maybe it is just smaller WU, maybe it is because of the 100% CPU set - the client is using 90+ % CPU (should be so), who knows. But the efficiency should be bigger I think :)

I found that although the BOINC screensaver was set, there was set also Avast antivirus screensaver - the AV screensaver does not change the "original" screensaver, but while is the ScrS in effect, the AV scans automatically for viruses and thus steals some of the CPU time. Maybe that was the problem, I set the AV ScrS off and it seems that the BOINC work speed up a little. I will observe it more, hope that it was the problem and thus it is solved.

Thanks for all your replies and advices :)

I have also checked my cpu efficency and it says almost 97.
But in my case the actual finish time for a WU takes longer than the estimated time by BOINC. And even the estimate says over 3 hours, but in UD agent I could crunch a whole HPF2 WU in about 1h and 40min.

But maybe it is just an other set of WUs that are larger.
