I have already installed tomcat server and I used sar for monitoring.



After tomcat has been installed my server sys user is taking 200% of CPU. Total quantity of cores is 4.



Please suggest me what I need to do ?

  • In a 4 core system load can go up to 4 * 100% = 400% CPU utilization before your system starts to become overloaded. - At 200% you're still good
