AUSST Client Update Performance

Hello,

i had an internal Adobe Update Server installed with AUSST and an IIS8.5 on Server 2012R2 - the Clients are getting the updates, but the download performance is very slow - between 5 - 10 Mbit.

Is there any chance to get an higher performance? the server has an 10gbit network card and all clients have 1gbit.

regards
