Rsync I haven't throttled bandwith usage, but have capped the max number of concurrent connections.  Unless someone is creating a fresh copy of the mirror, then rsync is rather efficient.  I also do not see a lot of users connecting over rsync.

If you are using vsftp, then you could add something like this to your /etc/vsftp/vsftp.conf:

# Max transfer rate 10 Mb

HTTP I haven't looked at that much, but EPEL has mod_bw that restricts the maximum connections and bandwidth.  I have not tested mod_bw though, as bandwidth luckily hasn't become an issue yet for our mirror...
