Hi, without any profiling data - just with the "feeling" value there won't be any help for you.
You need to identify a typical use situation where darktable 2.0 "feels" slower than 1.6.9. Then you need to reproducably measure the timings with '-d perf' (or '-d opencl -d perf') once for 2.0 and then for 1.6.9.
