# It's possible to run ppp back-to-back with itself. This is useful
# for testing.
#
# When testing scalability and concurrency, the following profile might
# be used.
#
# Note, you'll have to make some other machine adjustments:
#
# o Bump maxusers in your kernel configuration to about 256 so that there
# are enough process table slots.
# o Bump system file descriptors with ``sysctl kern.maxfiles=20480''. You'll
# need 3 descriptors per ppp process (assuming no server socket).
# o If you're not using DEVFS, create device notes with
# ``cd /dev; ./MAKEDEV tun5000''.
#
# You can now create 2000 processes (1000 pairs) with:
#
# n=0
# while [ $n -lt 1000 ]; do ppp -b loop; n=$(($n + 1)); done
#
# If you want to test concurrency, try using ``ppp -dd loop'' instead.
