Hi Koti, There is not much between a daemon and not daemon thread in the JVM so until you:
* start tomcat in an already (over)loaded environment (OSGi, multi-server instances) or * have some agent or plugin using AttachCurrentThreadAsDaemon extension point there is no reason using yield would help. So high level I think it makes sense for you to create instructions to reproduce the issue (you create a github repository with scripts or a readme to explain how to evaluate and identity this slowness for anyone willing to help on this topic) cause technically it looks like you don't fix the root cause of your issue but a side effect.
