First, I'd like to say that I use JRuby a lot, and you guys have done an amazing job on it. I complain because I like JRuby, and wish I could use it more :)
I did set the Xmx and it still uses around 80MB. I'm not sure what in the world the JVM is doing there, but the permgen is another 20MB or so and then other native stuff, thread overhead, etc.
Is memory cheap? Yes and no. At work we have a rails site with two REST api backends both ruby. I also love RubyMine. Now here's my problem, I can't run all of those on the JVM on my macbook air. 4 gigs is not enough if I also have a browser open!
This is not a problem at all if I switch the apps to MRI and switch my editor to a non JVM based editor. I think the JVM people need to recognize this problem.
