This is the third part of a series about migrating a large application from XAF 12.1 to XAF 15.1. In this part I will compare the results of a simple stress test between the versions.

I have described in previous posts how to stress test XAF applications. One of our most basic tests is to simulate 25 users cycling through all the navigation tabs for an hour. I’m happy to report there is a considerable improvement under load in version 15.1.

(Note that we purposefully stress test against a single web application so that we can compare apples with apples. In production we have multiple instances load-balanced.)

Here is an interactive summary of the 15.1 results:

Here is version 15.1. There were zero errors and 382 completed scripts.

By comparison, the same test against DevExpress 12.1 yielded only 258 completions. So 15.1 shows a 48% performance improvement over 12.1.
