Hi guys,

as you may or may not have read, I'm working on a patch which drops the
need to maintain /etc/passwd and /etc/group files, but rather loads all
required information from Windows (either SAM or AD).

It's all working pretty nicely already, but there's one part of my
changes which is a bit, let's say, questionable in terms of memory
usage, *iff* a user decides to stick to the passwd and group files.

To learn what I have to struggle with in this situation, I'd like to
know this:

  Is anybody here who's using /etc/passwd and/or group files
  of more than 16K in size?

If so, please reply to this thread with the size of your files.


Thanks in advance,
Corinna


P.S:  As a sidenote, if you think Cygwin is slow, one factor *might* be
      the size of your passwd and group files.  Right now, these files
      have to be loaded anew in each exec'ed process.
      This is supposed to go away with my patch, but big passwd and
      group files would still have an impact when starting the first
      Cygwin process (mintty, for instance).
