Yes, quite possibly, or maybe the other way around - from one of the workers. The --prof flags gets passed on to the workers but the problem is that it either creates a garbage v8.log (because it contains entries from multiple processes) or that only one process actually gets to write to it, the last one that opens it. What you can do as a workaround is to pass `--logfile v8-%t.log` on the command line and make sure that each worker is started with at least a one millisecond delay. %t gets replaced with the timestamp in milliseconds. > The CPU of the 3 workers was pretty much pegged for the duration of the > profile > > Thanks, > > Chris -- 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.
