  That should be fine.

  I've run it at 40K packets/s for days straight.

  Yes.

  Wow.  For 2M users?  Don't use the "users" file.  Use a real DB.

  Though I have tested the users file with many millions of users.  It
uses a lot of memory, but it works.  The server puts the entries into a
hash table internally.  So it has the same performance for 1 user, or 2M
users.

  Do lots of tests.
