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 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.
