Query is fast, but long lag before page is rendered

Question

Good morning, all!
I have a page that runs a query that returns 518 records. The
page is taking about 9 seconds to load. I added code after the
CFOUTPUT so that I could check the speed of that section and that
shows me that the CFOUTPUT finishes looping over the query after 3
seconds. The CFOUTPUT block is the last code on the page; just to
be sure, I added a window.defaultstatus = 'done' as the line
immediately before the closing body and html tags. The status bar
shows 'done' and then it takes between 5 and 6 seconds before the
page renders.
I realize that this is probably not a CF issue, maybe a
browser setting? Our standard is IE 6.0, which is what I am using.
Any ideas, war stories, resources, or references would be
greatly appreciated.
Thanks,
Kathryn

How much content is being delivered to the browser. Once CF
is done,
all information in the page must make it down the pipeline to
the client
and then the client has to render it.
If you are doing a lot of looping and|or calculation as CF
builds the
request, you could be generating a mind boggling amount of
extraneous
white space.
There are many ways with which one can use to mitigate some
of this
white space. <cfsilent>, <cfprocessingDirective>
and <cfsetting> tags.
Settings in the administrator, and just restructuring your
code to
reduce white space to name a few.
