IE9 is slow in XenApp 6.5 Server 2008 R2

I am testing our new XenApp 6.5 farm. We currently publish desktops to our users.

IE9 when inside the users published desktop is extreemly slow on any site with graphics (which is 99.9% of them). Basic sites like google seem to work OK, but anything more complex crawls, Eg Yahoo.com

I have all of the appropriate Flash & HDX software installed. Links are decent speed, there are no latency events (ping response normally between 5-7ms).

I have also scaled back all of the visual and audio qualities to minimum and the speed is still slow.

We have the Citrix Enterprise receiver 3.4 installed (also tested with 3.3 & 3.2 with the same result).

Just to add, printing from within a published desktop session also seems to be slow (eg when printing a word document, I select the printer which will take 5-10 seconds to refresh, then again if I want to make any format changes, then again after I click print).

So perhaps it is not related to IE9.

Everything else seems to run smoothly.

I changed the setting as suggested in IE. It didnt really make much difference. You are correct that It is a VM (ESXi 5.1) and it is using the generic VM Video drivers. Should I have installed different drivers?
Have you tried opening resource monitor and watching the Iexplore run and see if what sub processes it is calling?

You may also assign more video ram to the VM and see if that helps.
Are these flash or non flash sites?

Tried all of that. Still no change. I might just revert back to IE8. I have preped a new server with this and it is much faster than IE9.

I have been researching and majority of the documentation online (mostly from Citrix itself), states that IE9 is not supported as the HDX Client rendering does not work. They also say to use IE8, which supports my comment about IE8 being much faster than IE9.

Only thing is though, all the papers I read were from 2011 and early 2012. I was not able to find anything to show that this bug has been fixed yet. My concern is that IE8 is no longer supported by Microsoft & that IE9 is now installed as a critical update rather than an optional one (IE10 is now the optional Update).

So unless Citrix has resolved this HDX client rendering issue on IE9, I guess I have 2 options:
1. Run with an unsupported version that works (IE8)
2. Try IE10 and hope the issue is resolved in this version.

Just to clarify, this issue impacts IE when users launch from within their Published Desktop. It is not related to the local Browser.

Or a 3rd option I guess is to try a 3rd party Browser (eg Chrome, Firefox), however if these do work, I will loose a fair bit in being able to manage browser settings.
What happens if you publish the 64-bit version of IE instead of the 32-bit.  I have a similar problem and a workaround I found was publishing the 64-bit.  Chrome and Firefox are also slow.
