I love to go fast. I love fast cars and I love fast software. In fact, earlier in my career I used to specialize in software performance.
That’s one of the reasons I’ve been so excited by the performance improvements in the recently released XenServer 6.5. You can read my last blog on the features of XenServer 6.5 for more details on the speed improvements. While it’s great to do your own measurements to track improvement over time, it’s even more fun and rewarding to see others validate your results for you.
IBM published a new Redbook reference architecture for how to implement Citrix XenDesktop on top of Lenovo servers a couple of weeks back. In this reference architecture, IBM compares various configurations for running these virtual desktops. In one set of tests, IBM does a very direct comparison of using VMware 5.5 and XenServer 6.5 on top of Intel XeonE5-2600v2 processor family servers to run Shared Hosted Desktops (see tables 13 & 14 in the Redbook). Here’s a quick summary of the results:
IBM goes on to note, “XenServer 6.5 performs better than ESXi 5.5 for hosted shared desktops.”
Obviously, all those performance improvements that went into XenServer 6.5 are really paying off in real world applications!
Want to learn more about how we’re getting these performance improvements in XenServer? A few years back the organization put in place a dedicated performance team responsible for driving performance forward for the platform.
