Re: Is VM size an architectural smell?

The heap size may be a faint whiff. However, if there's a problem it'll most likely stink the place up in the form of genuine impact to your system's behaviour.

Sensible metric capture, even simple GC logging, will typically show issues fairly readily. They will also continue to demonstrate whether all is well for the lifetime of your software.

A similar smell, in my experience, is setting GC parameters at all (logging aside). A reasonably well designed and written app will typically be pretty amenable to GC ergonomics. YMMV, but I've seen these properties used most often in an attempt to keep a struggling JVM on its feet.
