Vendor Case Study Healthcare – McKesson & Citrix XenApp

By | October 1, 2014

Equipped with ExtraHop, the McKesson application hosting team found that failed  DNS record lookups were adding significant latency to Citrix launch and load times.

Each failed DNS record lookup took approximately five seconds to resolve, and some application launches triggered more than five of these lookups. By removing bad records, McKesson saw average application launch times drop from 40 seconds to 12 seconds—nearly 75 percent faster.

• 90% reduction in mean-time-to-resolution (MTTR)
• 75% improvement in Citrix launch and load times
• Avoidance of SLA penalties
• More than $660,000 in annual cost savings
• Retirement of legacy infrastructure monitoring tools
