In my experience, DataViews are way slower than typed arrays, and it's a known issue <https://bugs.chromium.org/p/v8/issues/detail?id=3533>. They delegate to C++ instead of generating code at runtime for it (with just SMIs, it's comparable to a standard function call in generated assembly length), which is probably the bigger slowdown (it's faster there than even in normal JS).
