Hi, I did the comparison also with DT 2.2.3-1 from experimental and a self-compiled binary. The result is the same:
self-compiled (opencl deactivated): [dev_process_export] pixel pipeline processing took 14,006 secs (108,940 CPU) binary from experimental (opencl deactivated): [dev_process_export] pixel pipeline processing took 21,900 secs (171,644 CPU) Matthias
