Have you tried measuring how much of the startup time is in
hostname lookup? I was able to shave off a whole second just
by configuring ERL_INETRC to use the hosts file 1st on one
particular system where I had quite noticeable startup
delays.

Also try
-connect_all false
as a test.

On my Linux machines the VM usually starts up fast enough to
be negligible when used via escript.
