Appeon Server installation program will not bind the instance to CPU. You must manually bind it with the following steps:
Open Windows Task Manager, select the Processes tab, select the server process, such as jagsrv.exe, right click it and select Set Affinity from the popup menu to bind the process to one or more CPU.
Or you can use the Appeon Server Status Monitor to automatically bind the server instance to CPU using the "com.appeon.server.monitor.instance.cpus" setting. For detailed instructions, refer to the the section called “Configuring Status Monitor” in Appeon Server Configuration Guide for J2EE.
