I have a 512 MB server on Linode.I launched htop and it lists a main process and 18 subprocesses (workers); that too on idle. Each subprocesses are listed to take 8% (or 40 MB) of my total memory. But its obviously shared as memory consumption increases by a total of 40MB when I launch Tomcat.
I intend to run Solr on this system and I am worried about the resource consumption under load. Do you recommend limiting the number of workers in a VPS environment? If so, how do you do it?
