The Thrilla in California: Debating Hypervisor Performance For the past 2 years, Citrix and VMware have used the blogosphere as their virtual sparring ground for a debate on hypervisor performance. While each vendor has contributed a wealth of information on virtual infrastructure performance to the online community, both continue to passionately disagree on how their respective hypervisors stand up to enterprise-class production workloads, as well as how best to measure performance in virtual environments. In this debate, VMware and Citrix have offered their most knowledgeable and passionate voices in the realm of virtual infrastructure performance: Simon Crosby (CTO - Citrix) and Scott Drummonds (Manager, Technical Marketing VMware). In this fast-paced debate, come to hear both vendors take off the gloves and get to the bottom of where their hypervisors stand with regards to performance. Attendees will have an opportunity to provide questions for the debaters, and the following topics will also be addressed: • Technical nuances that offer the greatest performance benefit/detriment to VMware and Xen hypervisors • Effective methods for measuring hypervisor performance • Barriers to performance scalability (Javascript is required to view Mediasite content)
