Dear Utkarsh: I was talking about CPU multi-threading, that is, using multi-cores, e.g. http://www.vips.ecs.soton.ac.uk/index.php?title=Benchmarks#Results_in_detail And unfortunately, I am swamped, and consequently, I basically can't help. I may be wrong, but I am pretty sure that GEGL does not multi-thread as of now.
