How can I reduce vert.x memory consuption

Question

I read this post: https://groups.google.com/forum/#!topic/vertx/VuKsUzUah88

and I don't know how to access the DEFAULT_JVM_OPTS in the current vertx version.

I tried following command:

java -jar myapp-1.0.0-snapshot-fat.jar -conf config.json -Xms128m -Xmx400m -XX:MaxPermSize=128m -XX:ReservedCodeCacheSize=48m

and doesn't seem to hava any effect to my apps mem consumption. do you have any advice for me?

thanks in advance

你有没有尝试过

java -jar myapp-1.0.0-snapshot-fat.jar -conf config.json -DDEFAULT_JVM_OPTS="-Xms128m -Xmx400m -XX:MaxPermSize=128m -XX:ReservedCodeCacheSize=48m"
