@erichelgeson, it's running on jdk8 now. Any advantages to 11? Don't know what the original usage was as such, because it was one of a number of webapps running on Tomcat on a machine with 4GB RAM and it was never important enough for me to do any memory profiling. For no other reason than curiosity, I tried it with 'JAVA_OPTS=-Xmx150m', but that didn't work, running out of heap memory on the one complex action. I'll probably bump it up to 250m now I know that, just to be on the safe side. The important thing about this, though, is that it shows I can reasonably deploy 2-3 small Grails apps within a minimal spec VPS, which really brings the cost down. It kind of means I can spin up a little Grails app for pretty well any purpose without having to consider hosting costs.
