The shallow size is the size of the object itself, the retained size is the shallow size + the size of all objects this object directly or indirectly points to. Example: var a = { /* empty */ }; var b = { a: a }; var c = { b: b }; The shallow size for all three is (for example) 24 bytes. The retained size for |a| is its shallow size because it doesn't contain references to other objects. For |b|, it's |a + b|'s shallow size and for |c|, it's |a + b + c|. The summary view gives you a breakdown on a per-constructor basis (i.e. the class name.) The comparison view lets you see heap growth (or shrinkage, as the case may be) between snapshots. Note that you need node-heapdump v0.3.0 for that to work properly. The comparison view is indirectly also part of the summary view: you can get a summary of objects created between two snapshots. The containment view is a breakdown of allocations per subsystem. It's not that interesting for node.js applications, although it can give you a quick estimate of how much memory is locked up in buffer objects. Hope that helps. I will add the above to the README someday. :-) -- Job board: http://jobs.nodejs.org/ New group rules: https://gist.github.com/othiym23/9886289#file-moderation-policy-md Old group rules: https://github.com/joyent/node/wiki/Mailing-List-Posting-Guidelines --- You received this message because you are subscribed to the Google Groups "nodejs" group.
