I’ve been using Micro Focus LoadRunner to do performance testing on Allscripts Sunrise Clinical Manager (SCM) since version 4.5 in 2005. I have learned a lot over the years. As with many EHR/EMR applications, the deployment method is usually Citrix XenApp or XenDesktop as a published application. This requires using the LoadRunner Remote Access protocol group, which is basically the Citrix ICA protocol.
Here is a link to a white paper I wrote on the topic. I hope this is helpful for those preparing for their first load test exercise and knowing what to expect:
With my previous company, we did a webinar on the topic, and it is available on Youtube (embedded below):
I also presented this information in April 2017 in Chicago at the Allscripts conference.
If you need consulting help or a LoadRunner expert to help you test your EHR/EMR, contact me. I can either help you directly or reference you to a qualified resource with the right kind of experience you need.
