HI Sergio,
Since there are certain parameters which are no longer used in the Tomcat 8 as compare to Tomcat 7 there is one important parameter is to clean the garbage memory.
Follow below options to add it to the java command line option :
- Remove the paralleroldGC parameter and add the parameter : -XX:+UseParallelGC
- Remove the permsize as it is no longer supported in tomcat 8.
- Check if you have minimum 4 CPU core installed.
Regards,
Mahak
