I don&#x27;t even know what we&#x27;re arguing about anymore. Do you dispute this?<p>&gt; (Netscape 4&#x2F;Opera&#x2F;IE) didn&#x27;t have a JIT, didn&#x27;t use hardware accelerated layers, trapped into kernel mode for GDI calls, didn&#x27;t use accelerated SIMD for painting, and didn&#x27;t have HTTP 2. It barely had any optimizations for dynamic restyling, so tons of stuff would get reflowed when it didn&#x27;t have to.
