Hello all, I need your expertise... please help me! (Disclaimer: I am a relative newcomer to 389ds) I'm running a Java application that keeps user authentication, permissions, and preferences in ldap. And I'm currently load testing this application (using Jmeter, 15 concurrent threads, no think time) and I'm getting really good performance most of the time. However every 5 minutes (from the time I started ldap), 389's CPU usage will spike to 375% (400% = all 4 processors at 100%, 389 normally sits around 15-20%). These pauses last for between 20 - 30 seconds (proportionate to the load I'm throwing at it) during which our application will just sit. Since I'm just running the same set of requests at it constantly, there isn't anything different in terms of our application during those times, which points to 389 as the culprit (or possibly some glassfish ldap pool problem). Some info: Glassfish 3.1 final on Java 1.6.0_26 (64 bit server VM) 389-Directory/1.2.9.10 B2011.250.1455 Fedora 15 64-bit (also observed on Centos 5.4 64-bit) Have any of you run into this problem? Do you have any possible config changes I could try? Any possible leads at all?
