# note that we point uploads to port '9970', do this when you want to
# run in a configuration where you have two siad instances, one for
# downloads and one for uploads. This drastically improves the up - and
# download speed of your portal. When running your portal in this double
# siad setup, make sure only the download portal runs in 'portal mode'.
# The upload siad can be run in normal mode. Set the port to '9980' if
# you do not want to run your portal in the double siad setup.
