For a while now customers and colleagues are asking me which tool to use when it comes to CPU scheduling and Memory optimizations. We use several management products and end up with more than one product utilizing these tasks. Choice is good but do we just enable them all and if not what’s the best way to configure this?

When you look a little bit deeper then plain and simple marketing you’ll notice that the way the different products handle memory optimization totally different and combining some of them will degrade system performance or might not work.

To start off I will first try to explain how each product works and will then summarize and see if we can work through them and work to a proper advice.

When you look a little bit deeper then plain and simple marketing you’ll notice that the way the different products handle CPU scheduling is totally different and combining some of them will degrade system performance or simply don’t work for example Citrix CPU management does not start when Microsoft DFSS is enabled.

Before we start I’d like to thank Andrew Morgan for allowing me to re-use some information from his ThreadLocker topic.

To start off I will first try to explain how each product works and will then summarize and see if we can work through them and work to a proper advice.

When working in Enterprise or even multi tenancy environments we would still like to maintain a single image for our entire infrastructure. This will ensure a lower TCO and have a simple and easy to use platform to maintain. Departmental application with RES Automation Manager.

When we started working on our cloud desktop offering the “Qwise Nebula Worqspace” over a year ago we ran into issues with applications that don’t like App-V but were very keen on managing only one Provisioning Services image . As we were already working with RES Automation Manager the first thing to look at was the functionality offered by RES Automation Manager (AM) and we found a solution for this! I will tell you how and when this helps in this article!

Over the last few years we have worked with a lot of customers and partners who use(d) Citrix products like Citrix XenApp. Not all of them are, to say the least, “happy” with it. My article focuses on “how did that happen?”.

It all started some years ago with Presentation Server nowadays called Citrix XenApp. We have heard them all “Citrix XenApp is slow”, “Citrix XenApp is unstable”, Citrix XenApp is hard to use and one of the best “don’t virtualize your Citrix XenApp servers”.

I will not go in to details about all of the issues customers are experiencing because this article would end up as a book. What I want to focus on is the big picture.
