You must be comparing previous cpu time with current elapsed time. As the cpu was really doing nothing even before, it is likely that 1 h cpu time corresponds to 1.1 hours elapsed time.

GDF

Under Windows I have much less using CPU time with 0:43:38h CPU time and 9:26:48h elapsed time with the 6.45.

WU with 6.45

That's 1 hour CPU time to 12.99 elapsed time (or GPU-time).

With the 6.43 the CPU = elapsed time was 7:50h, so the WUs need much longer with the 6.45 by less CPU usage.

WU with 6.43

And btw: I use the free time for another task through the cc_config.xml and the ncpus-entry. Give one more than exist and 5 tasks are running on a quad.

It is possible that faster cards as yours suffers more with the new app. Could you try to run with just 3 other jobs to see if the GPU time reduces?

The first 3 WUs with the 6.45 I've crunched without the change in the cc_config.xml. The CPU time was 2618.57 (34008.726 elapsed time) and 3084.76 (35277.078 elapsed time) with ncpus=5 and 3484.17 (36270.111 elapsed time), 3082.61 (39698.400 elapsed time) and 3681.14 (30449.058 elapsed time) without.

You can find this here, TaskIDs 59992, 60120 and 60200 without ncpus-entry and 60334 and 60539 with ncpus=5.

I was referring to the GPU time. Anyway, your is approx 40 ms/step. Independently on how many cpu jobs you are running, which is good.
