Please sync to head. Patches 7.3.1137 and others have improved performance a lot. I was just looking at Javascript highlighting and there the new engine is almost twice as fast. I am still looking to find places where the new engine is slow. Please use :syntime to find out. The files I collected are for checking correctness, I haven't setup something for performance yet. It is not so easy to measure the performance in a reproducible way, Vim is too clever skipping redrawing when it's not needed... -- hundred-and-one symptoms of being an internet addict: 109.
