Erlang isn't particularly fast in startup time, but I've never seen it take more than a second, even on a fairly constrained machine of the modern kind. My bets are: - Antivirus messing with File I/O - DNS - You run in a VM and it has been given almost no resources - The system is waiting on timeouts for calls which fail In a UNIX system, I would recommend to use strace/ptrace/ktrace/dtrace to figure out what is keeping the program in a stalled state. I don't know what to use on Windows 10, but I can't imagine there is no equivalent tool. -- J.
