Quite possibly the No. 1 complaint you hear from your end users is frustration about the speed — or lack thereof — of their Citrix XenApp or XenDesktop environment.
You and they both know that not only is a slow system inordinately annoying, but it’s also a productivity-killer. Moments spent watching the blue donut of death are precious moments your staff isn’t helping the business grow. and those moments add up.
As an IT manager, your quest is to make your IT environment run smoothly. Is Citrix XenApp or XenDesktop a thorn in your side? Citrix application and desktop virtualization is good stuff. It just has to be architected and managed properly. From what we see every day in our work with firms large and small across the country, here are the top 5 reasons Citrix is slow:
- Misconfigured profiles — , Proper time and attention was not given to selecting the correct profile type or thinking through the size of the profiles, or how and where the end-user data should be stored to deliver the right balance of performance and individual customization.
- Improper OS optimization — The OS was not optimized properly when it was initially set up. Microsoft operating systems are not optimized out of the box for Citrix XenApp or XenDesktop. We have cataloged approximately 100 of these optimizations alone.
- Run-away processes — These need to be managed, shut down and, optimally, prevented altogether. In these shared environments, preventing one runaway rogue Excel spreadsheet, for example, from impacting the end user performance for the other users trying to get their work done.
- Insufficient capacity — This isn’t as common as some of the other issues we see that make the Citrix experience slow, but it’s one to watch out for. Sometimes cookie-cutter Citrix environment builds fail to take into consideration the specific needs of the particular customer. We see undersized virtual machines, insufficient RAM, and inadequate network bandwidth. A slight variance at a very large scale can have a significant impact.
- Insufficient staff expertise — This is not a knock on in-house teams, by any means. Citrix is a complicated beast that requires the coordination of several sub-systems (SQL, Active Directory, storage, etc.) to perform properly and deliver an optimal experience. Poor design or a failure to understand how any of these sub-systems impact Citrix performance consistently leads to a less than desirable end result.
Ok, I get it, but now what?
Citrix is slow and you want to fix it. But is it really Citrix? Citrix is only to blame 20% of the time according to our internal statistics. Perhaps the problem actually lies in any of the 13 systems that Citrix relies on to complete the delivery experience as part of your overall infrastructure. A slow Citrix environment can be attributable to any one of these infrastructure pieces gone awry.
As you begin to analyze your environment, you’ll want to consider whether remediation is possible or if a complete rebuild is necessary to correct the issues.. Often, a remediation will get a slow Citrix XenApp or XenDesktop environment back on track, but not always. A careful assessment of your entire environment is required to make this determination.
