Plask profling

[vorg]

I've been following this guide on how to make a flame chart from node v8.log profile and they mention

With a version of node that has a --log-timer-events as part of v8-options, run the app in profiling mode and load the resulting v8.log into Chrome at chrome://tracing.

Is --log-timer-events a compilation option? My graphs are empty so not sure if these log timer evens are properly logged. I'm running:

Plask.app/Contents/MacOS/Plask --prof --track_gc_object_stats --trace_gc_verbose --log_timer_events main.js

Any other ways to profile a Plask app?

Yeah, I've profiled plask many times, in general --prof works and writes out v8 log files, but there will be more than one log file, because the log file is per context. You need a tick processor that matches the right version of v8, which is the only tricky bit, but I've done it a few times before and gotten good profiles.
