No sites in particular; it's just noticeably less snappy than Chrome (on Android anyway - the difference on desktop isn't really noticeable).

Ah, I can definitely see mobile being a different story. Google is probably pouring immense resources into performance there as it directly affects battery life, just like Apple does into Safari.

I'm unfortunately on the latter platform, so I'm limited to WebKit chrome wrappers for the time being.
