5 out of 31? And I'd say only 3 are noticeably slower, and only 1 seems to be "much" slower (at 0.38ms). But given that just about everything benchmarked seems to be sub-0.05ms, I'm left thinking that gaining noticeable and much-increased performance is highly dependent on operations, and a high-precision timer. Humans aren't going to notice a difference between an operation lasting 0.04ms vs 0.02ms. Unless a ton of operations add up to something noticeable, of course.
After looking into it further, morphdom appears to be a solid alternative to virtual DOMs. Seems worth having around for that reason alone, especially if it were to improve with time, or become used by other tools.
