Yes and no. They're strictly for snapshotting the V8 heap but embedders can provide information about external objects and node.js does. For example, a Buffer consumes only a few bytes of on-heap memory but potentially many megabytes of off-heap memory. Node.js provides some metadata to V8 that ends up in the heap snapshot and lets e.g. Chrome's inspector tool show the object's true size. -- -- Job Board: http://jobs.nodejs.org/ Posting guidelines: https://github.com/joyent/node/wiki/Mailing-List-Posting-Guidelines You received this message because you are subscribed to the Google Groups "nodejs" group.
