Hello Community Members,

I am working on a performance engineering project for Crawford desktop application developed on Appian framework and we have been executing multiple rounds of load tests with concurrent users starting from 50 to 300.

It has been observed throughput the load testing exercise that the application response times were not stable beyond 200 odd users and are increasing drastically. We are trying to find the bottleneck for the high response times and related performance issues.

As a matter of fact, we need to breakdown the response times across all layers of request-response communication so that the area of concern could be identified and hence we can consider it for the performance optimization. We tried running the webservice load tests in order to check if webservice calls are taking too much time to fetch the data from back end DB, however this was not the case, so now the focus area is the Appian infrastructure.

Here...

  • You can see more information about the nodes in a process instance by going to process details > process nodes tab.
    Have you been able to use Fiddler to see the response times with Appian and your web server?
    Try increasing the logging to find out what could be causing the performance issues.
    Do you have any custom plugins? If so, do you experience a performance issue more with these plugins, or is the issue across the system overall?
    Are you query a database multiple times? How much data are you returning from your database? Can the values be reduced to a view?
