The data is being extracted on the server. The resulting html is being
created on the server. I don't think it cares too much what browser is going
to be recieving the results.
In this case it would appear to be a rendering issue. The final html page
that is pumped out to the browsers must be taking longer to render on some
browsers than others, and that is not a php issue.
Although the resulting markup does have a !DOCTYPE declaration, it doesn't
validate. That is going to give inconsistent results on different browsers.
You make a contract with the browser, then immediately break it.
On my machine, in Australia, it takes about 3 seconds to load and render.
I'm running IE6.
I think if you output code that meets the requirements of the declaration
you results will be more consistent

Yes, but it's the final html the script is generating that is the real
issue.
