What if the browser doesn't cache the html, but some parsed and validated memory dump of the document? Then you'd be comparing the cache systems too. Maybe it'd be better to load from localhost without caches.

Programming in D is nice, but the situation is a bit annoying.

1. Tango vs Phobos. Phobos is the official standard library, but it seems most use Tango. Phobos is also pretty low level compared to Tango.
2. The reference compiler dmd is 32bit only, gdc is outdated and abandoned, and ldc is still alpha status and has missing features. Ldc is quite promising though.
3. D2 is maybe the biggest issue. It has very useful features, such as partial C++ compatibility, but D2 is a moving target and practically no library supports it. It's also unknown when or if ever D2 will become stable. I haven't seen much discussion about it in the newsgroup either.
