And these are the results on openmoko freerunner gta02, not a fair comparison since the webit version is older, 1.2.1 vs 1.3.3+git and i've used different browsers, midori vs gtklauncher. Said that the improvement is huge i'm pretty confident the arm jit helps.

The numbers are on par with chromium (bit slower actually) on the same hardware and same os. See

midori + libwebkit 1.2.1:
