Poor Performance of Citrix Receiver 3.4

My company are in the process of upgrading our Citrix XenApp image to include hotfixes and new versions of software for Flash, Reader and the Citrix Online plugin.

Currently we use plugin 12.1 which works pretty well overall.  The only real issue we see with this is connecting to other companies access gateway infrastructure if they are using Web Interface 5.3 using IE9.  We have a workaround for this, but fixing the problem would allow us to ditch a couple of servers.


So we planned to upgrade the plugin to the latest version which supports PNA.  Version 3.4 is the latest versions available to download from the Citrix website.


We installed it using the string I have discussed numerous times on this site.  This ensured that the receiver element was at a minimum.


We tested this for a while and noticed that performance to Citrix XenApp application based on XenApp 6.0 was great, but when connecting to our old farm which is based on Citrix Presentation Server 4.0 the performance was awful!  The screen refresh was incredibly slow, mouse clicks wouldn't register and overall it wasn't acceptable.

We decided to install the previous version (3.3) which is still available on the Citrix website.  This is unusual, typically software vendors remove old versions of software when a new release has arrived.  This could suggest there is a known issue with 3.4.


Once 3.3 was installed, performance to both our farms was perfect!

So if you have installed version 3.4 and are having performance problems check out a downgrade and let me know how you get on.



  1. I can verify that. Just uninstalled Receiver 4 and installed 3.3 and my performance connecting to a PS4 server is night and day. Wonder what changed in 3.4 forward?

  2. Very interesting article and your example of it. I would recommend that you use the cloud server, so you do not worry about its performance virtual data room reviews
