Many thanks to all of you for your help. Nevertheless my performance
problems persist. To set opencl_use_pinned_memory=TRUE yields no
perceivable improvement.
Before I reinstall DT I'll try and install a mouse to see if there are
some differences in behavior. If I need more help I'll open a new thread.

I don't see anything specifically broken here. Let's take for example
the snippet from the quote below.
Time spent in OpenCL kernels including memory I/O is 0.055 seconds.
Total time in pixelpipe is 0.123 seconds. There is a bit of overhead
here but that's not dramatical. You may try to set
opencl_use_pinned_memory=TRUE which might improve this a bit.
Overall the time spent in this sections is between timestamps 130.658s
and 130,781 which matches the figures above.
I'd say if you are losing performance it's probably not in the pixelpipe
and likely not OpenCL related. That also fits to your observation that
you don't see a difference with/without OpenCL.
