Will do.
For now I deleted nvidia-361 driver and switched to nvidia-340 (340.96).
So my export time with OpenCL dropped from 124s to 27-30s (5-8s better
than CPU). The output is updated here :

Those timings look much more reasonable. About 9 seconds are spent in
OpenCL kernels. The rest is spent in several non-OpenCL modules (e.g.
colorin/colorout with LittleCMS2, defringe which lacks OpenCL atm).
