In the Java JVM, kill -3 forces the process to print the current stack traces of all running threads. I found it very effective to quickly locate bottlenecks.
Is there an equivalent in V8? Can I make V8 print the current stack trace?
Clarification: I assume, due to the asynchronous nature of node, it will be less useful than for a typical non-asynchronous program. Still, if there is an easy way to get access to a few stack traces, it does not take much time to look at it.
From my experience, some obvious bottlenecks can be quickly located that way before you need to switch to more advanced tools.
