As I read this, I find myself wondering what you're actually testing. The
reason I ask is because you're discussing the rendering speed without
telling us how you're measuring it.
You could be measuring how long it takes for the HTML to be sent to the
browser, *or* how long it takes before the page is viewable by the user. If
you're measuring the latter, then I have to point out that the last time I
tried to render a table with over a thousand rows, it pretty much choked the
browsers entirely. Pagination was required.
If you're measuring how long it takes for the page to be received (for
instance, via wget), then yes, there's a whole different question.
For that, double check how your templates are being @expose'd. Make sure
that it looks like this:
@expose('chameleon_genshi:dotted.template.name')
and not this:
@expose('genshi:dotted.template.name')
That's all I've got right now, anyway.
