Um.. Tim..

The discussion concerns rendering time, not transfer time. While I
don't think it's clear exactly what we mean by "smudged" HTML I
interpret this conversation to be an observation of the fact that
articles like many nested tables, messy or contradictory code, or
non-standard code can slow down page rendering. In addition, more
descriptive HTML obviously means more MIPS get chewed in page rendering.

As well, I've noticed that web browsers have begun to render incomplete
documents, building the page as it, in effect, "streams" to the client.
This creates headaches when the dynamic data filling in a cell that
comes from an SQL query or some other CGI-type device actually modifies
the physical layout of the document. This creates tandem layout
problems -- the delay for the dynamic data, plus the delay for the
"re-evaluation" of the page when the browser realizes that the dynamic
data won't fit in the cubbyhole it created for it based on assumptions
drawn from the other data in the page.

Does anyone grok the rules for how this streaming works? I think it
changed around Netscape 2.0, and it didn't really become prominent until
ASP and more dynamic pages came around.
