I'm hoping that DH will take some note of this; their default web server configuration is using the old Apache behavior of modifying all responses to Microsoft Internet Explorer, regardless of version, and making them quite a bit slower.
Given, the old ones were broken in certain regards, but the newer ones are better; specifically, in the areas all of our web pages are being served.

Thanks for the suggestion. You're right - we're applying
SetEnvIf User-Agent ".MSIE." nokeepalive ssl-unclean-shutdown downgrade-1.0 force-response-1.0
which is probably harming performance on modern versions of IE. I'll open an issue for our developers to take a look at it.
No worries, I think it will give a speed boost to the DH pages themselves as well, of course.
Thanks for passing it on to the devs.
responses to this thread will be emailed to me, thanks.
