Tomcat java web application got running slowly

Don't know which way of investigation should select. After some time (near 4 weeks) on continouous running web application got run slowly. Checking:

catalina.out - no full gc.

Regular gc takes near 0.2s and executed one time in near 10 - 30 seconds. On the same server another tomcat with web application running well. So the problem not in the host. I am really confused. What should be checked ?

you can use a visualvm to track you tomcat performance, you have to add the JMX parameters to allow you to connect the visualvm to you your tomcat.

-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.port=8484
-Dcom.sun.management.jmxremote.ssl=false

In the visualvm >> Threads Tab you will see a button in the above right corner Thread Dump, this button generates a file called thread dump, this file contains the whole threads that currently live, generate a multiple thread dumps and trace you application threads, you will clearly see what does the slow thread is currently doing, which exactly the method caused that slowness.

I hope this help you to get the root cause for your slowness.
