> my small Javalin app uses four times the RAM at rest as my Express app did
Are you looking at used heap space or just the amount of memory used by the Java process? I have a few small Java services using vert.x and they hover around 7-15 MB of used heap space. For small services I usually just restrict the maximum heap space size because the default is unnecessarily large.
