Here is an article by Theresa Miller on how to diagnose the root cause of Citrix slowness. It's not always a Citrix issue that makes Citrix slow. A problem in the underlying infrastructure also affects Citrix performance. This original article by Theresa is posted here: https://24x7itconnection.com/2018/04/24/citrix-is-slow-how-to-uncover-the-real-cause-and-prove-its-not-citrix/.
As a Citrix administrator you are supporting architecture that can be complex, distributed and includes many interdependencies between the Citrix tiers and the supporting infrastructure. It is also extremely likely that you are supporting an environment with many different versions of the Citrix software. Citrix is typically a performance-sensitive application. A problem anywhere in the Citrix delivery infrastructure can impact performance, and in turn, end user experience. And, when a user calls and reports that Citrix is Slow, your troubleshooting process can become complex.
Today, let's assess how to understand how even though a user makes a simple statement that Citrix is Slow, it really may not be a problem with Citrix at all. We will also discuss how monitoring your Citrix environment can help expedite identification of problems, and their root cause.
When a user calls to report an issue, it's not always clear where the real problem exists – especially in a complex and inter-dependent architecture like Citrix has. To deliver Citrix services, many infrastructure tiers may be involved, including Active Directory, storage, drive mappings, hypervisor and more. Asking the right questions when a user call comes in is very important and having a very good understanding of the environment is invaluable for rapid problem resolution. Let's look at some problems, and then discover some of dependencies that could be resulting in the problem the user is experiencing.
Keep in in mind that these are places to start your troubleshooting process, but the real resolution may not be limited to what I have shared here today. It's technology, so there are more things that could be factors. This list provides you with the foundation you need to get the troubleshooting process started when the problem doesn't appear to be related to your Citrix deployment.
When considering your Citrix environment alone, one may argue that they can manually troubleshoot their deployment related problems. Although I would never recommend this approach because it's slow and time consuming. We have discussed some examples of interdependencies that can impact common troubleshooting scenarios within Citrix environments. There is a lot of value in having end-to-end visibility across your Citrix tiers and their interdependent tiers with a monitoring tool. Not only will you be able to resolve real issues more quickly, you can also engage other teams only when needed and with specific insights that can enable you to resolve problems quickly and keep your users happy.
