Seen this recently and at present have a workaround in place. Very strange issue insofar as the fix is slightly unusual in itself.
Certain published applications were slowing to a crawl post upgrade to version 4.4.1.
Found to be related to the connection preferences and setting application setting from “seamless” to “1024×768” did the trick. Still assessing resolution.
Came across this useful tip on Citrix eDocs when encountering a need for it. Interesting insofar as haven’t needed to edit the default.ica file sent from StoreFront.
- On the StoreFront machine, open C:\inetpub\wwwroot\Citrix\<Store Name>\App_Data\default.ica with an editor such as notepad.
- Under the [Application] section make then entries below:
This is to enable Real-Time Transport
; This is to Allow Real-Time Transport Through gateway
; This is to set audio quality to Medium
; UDP Port range
Be careful as of course with editing the default.ica in this this will enable UDP Audio for all users’ who are using that store.
As most citrix bod’s will know with the release of Citrix XenApp 7.0 onwards the local host cache facility whereby in essence a cached copy of the citrix datastore was kept locally was removed from the feature-set. This caused much discontent in the user community as it placed much more emphasis on having to ensure decent connections (100ms max in most cases) to the site databases otherwise the need for separate sites and all additional infrastructure that comes with that.
Since 7.0 citrix have been making strides reaching a solution towards this and other limitations that came with the solution, features like connection leasing and the like but still came with constraints.
Good news is with the release of XenApp 7.12 Citrix have come “home” again with the re-introduction of the local host cache facility.

Picked up this useful tip from the vCenter Server HA performance and Best Practices guide (see – http://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/techpaper/vcha65-perf.pdf)
Will see on Pg 23 it will refer to the fact that:
“As a best practice, it is highly recommended to pick a time period with a very light workload to enable VCHA. Otherwise, the newly cloned Passive node PostgreSQL DB could lag behind too much and not be able to catch up with the Active DB due to transaction logs on the Active DB getting purged on the Active node. We are working on adding archivelog support to address this issue in upcoming releases.”
Sensible advice, might mean weekend work for some folk mind 😦
NetScaler StyleBooks are an interesting feature as they can help with providing standardization in your NetScaler environment. They do this by simplifying the task of managing complex NetScaler configurations for your applications.
