Have you implemented OpenMRS? Please participate in the Implementation Site Survey. If you already have, thank you!
The objective of this page is to describe load tests that have been done on OpenMRS. Particularly I was interested in loading the web interface to simulate multiple users on a commercially hosted OpenMRS instance to see how it behaved and if it was usable for the quantity of users that we had (600 total, around 100 concurrent).
I found Saptarshi's post on Load Testing. Like him, I looked at Faban very quickly but found that it tested more the application itself, whereas I wanted to test it through the web to see what a user would feel having a US hosted OpenMRS instance from Chile in this case. So I decided to go with JMeter as well.
