There's a lot of behind the scenes work going on the first time a
page is rendered. Basically Tapestry is creating a kind of
meta-representation of your page, enhancing your page class, and doing all
sorts of behind the scenes grinding. The downside is that, yah, first page
render is slow. The upside is that, since Tapestry pools the pages, it's a
one time hit in production.
It does, unfortunately, mean that you have to deal with that
annoying pause in development, but it's just one of those things
unfortunately. The usual things will speed it up e.g. faster CPU, more
memory if that's gating, etc, but there's really no silver bullet.
I suspect there are some behind the scenes optimizations that Howard
will make when he finds them, but I wouldn't count on an order of magnitude
improvement.
