There are some load tests for cas, https://apereo.github.io/cas/7.0.x/high_availability/High-Availability-Performance-Testing.html
To eliminate some points of contention: 1. set up a file system store of services, https://apereo.github.io/cas/7.0.x/services/JSON-Service-Management.html (or in memory). 2. file system store of users, https://apereo.github.io/cas/7.0.x/authentication/Permissive-Authentication.html (or add to the default list: cas.authn.accept.users=casuser::Mellon,hsimpson::password,wsmithers::password,mburns::password) Search this user list for mentions of cas performance.

Hi ray, we are using the embedded tomcat with CAS and we are using in memory storage for ticket. I believe there is issue with cas's ability to process requests.

What are you using for ticket storage (in memory storage will be faster than database, etc)? See https://apereo.github.io/cas/7.0.x/planning/Installation-Requirements.html and other related sections.

Hi, I'm using CAS version 6.6.x with Zoom for authenticated Meetings. The CAS Server is running behind a proxy server. Following is configuration of CAS Server and Proxy Server : 8 Core with 8 GB Ram. Whenever there is a load of more than 50 users per second the CAS perfromance degrades significantly and the site becomes unreachable I have also tried implementing throttling but I have not got a breakthrough cas.authn.throttle.bucket4j.enabled=true cas.authn.throttle.bucket4j.bandwidth[0].refill-count=50 cas.authn.throttle.bucket4j.bandwidth[0].capacity=50 cas.authn.throttle.bucket4j.bandwidth[0].duration=PT1S Also i have tried increasing the tomcat configuration server.tomcat.accept-count=500 server.tomcat.max-connections=8192 server.tomcat.max-keep-alive-requests=100 server.tomcat.threads.min-spare=100 server.tomcat.threads.max=600 Any help or suggestions on how can i make it work. I'm expecting a user load of about 150-200 users per second. -- - Website: https://apereo.github.io/cas - Gitter Chatroom: https://gitter.im/apereo/cas - List Guidelines: https://goo.gl/1VRrw7 - Contributions: https://goo.gl/mh7qDG --- You received this message because you are subscribed to the Google Groups "CAS Community" group.
