Hi Ullrich, Benchmarking the file export is easy. I just have to parse the darktable -d perf output for lines with [dev_process_export] to get useful values. How would you benchmark the responsiveness of darktable? There are so many values in the debug output - I don't see which of them would represent responsiveness.
