I use only a few modules, bench.srw uses a lot more modules than I normally use. Hard to say, if I found a typical fullformat excample, but with my own fullformat example I see: 7,393864 [dev_pixelpipe] took 0,116 secs (0,300 CPU) processed `Gamma' on CPU, blended on CPU [export] All others are: "blended on GPU [export]" 7,393968 [dev_process_export] pixel pipeline processing took 0,608 secs (0,915 CPU) Complete log is attached. So my ff-36MP-photo is a lot faster calculated. My goal is to avoid to copy stupid settings from the old pc. Interesting is: Spitzlicht-Rekonstruktion' on GPU, blended on GPU [export] With the bench.srw it was calculated by the cpu. So the use of the cpu depends on something and not on the coding of the module itself. So my question, if some of these values should be changed, because the new system is a lot more powerful: cache_memory=1073741824 maximum_number_tiles=10000 metadata/resolution=300 opencl_checksum=3732205163 opencl_device_priority=*/!0,*/*/* opencl_mandatory_timeout=200 opencl_memory_requirement=768 opencl_micro_nap=1000 opencl_number_event_handles=25 opencl_size_roundup=16 pixelpipe_synchronization_timeout=200 plugins/map/max_images_drawn=100 plugins/map/max_outline_nodes=10000 > then there is > only one direction where OpenCL memory optimization could help: if > you can avoid the contrast equalizer module to use tiling. > > But there is not much to gain.
