QUESTION

In node.js --prof output, what is this strangely-named C++ function doing?

Asked 2020-Feb-25 at 14:53

I am profiling a heavily modified fork of JS Interpreter, running on node.js v12.12.0, using --prof, while it runs a short synthetic benchmark. In the output from `node --prof-process, I see that 63% of the program's runtime is spent in C++:

Finding DispatcherImpl isn't hard: https://github.com/nodejs/node/search?q=dispatcherimpl&unscoped_q=dispatcherimpl leads straight to https://github.com/nodejs/node/blob/5aaa7fee2e4a075d9123b885f9e8cda3de2a780a/tools/inspector_protocol/templates/TypeBuilder_cpp.template#L218. But that probably isn't what you're really looking for...

There was a bug in the --prof system for a while where C++ ticks would get attributed to the wrong function -- looks like you might be running into that. It's been fixed in V8 recently, but the fix hasn't rolled into a Node release yet.

As a workaround, on Linux, you can use perf to profile C++ code [1], while still using --prof for JavaScript; JavaScript ticks as well as the C++/JavaScript distribution should be reliably correct in --prof's output. On other platforms there should be equivalent generic profiling techniques.
