Answer 1

You can try :

1. nodetime: See the docs on how to profile memory. A blog on how to detect memory leaks. It can show the largest memory blocks in the heap.
2. node-inspector with v8-profiler: Heap snapshots may be taken and viewed from the profiles panel.

To use the inbuilt V8 profiler from command line you can :

1. To build from source: node-gyp configure build install
2. Or, if you have npm installed: npm install profiler (See profiler for more details)

You can see other profilers mentioned here and here.
