Use a non-Apple parent for Software Update Server
If you run multiple Apple software update servers in your organisation you can point them to another local software update server. This could save bandwidth costs not having to download the same files multiple times.
To point to a server that isn’t Apple’s, all you need to do is change one line change in:
/etc/swupd/swupd.plist
Find the key metaIndexURL and point it to your local server.
You could then use a DNS round robin to spread the load across multiple servers, or simply point individual clients are particular servers.
