I need to run two webapps on a ubuntu VPS but one(my own webapp) prefers to run in Tomcat & other(Solr webservice) is preferable in Jetty. But I think running a separate server for each webapp would be consuming more resources (like memory consumption would be higher) than both the webapps running on same server, isn't it ?
What may be the other bad if I run both Tomcat & Jetty on a single machine for production use?
