need to use more faster way to synchronize packages

Hi, groups[‘ALL’].

I need to copy packages from a build server to the other servers.
Currently, I am using “synchronize” to copy them. however, this kind of stuff is too slow if the target machines are very large.
Even if I am using parallel executions, It spent quite long time to complete. The counts of target machines are over 700 and the size of packages is over hundreds megabytes and I need to do them all under a max network bandwidth.

is there any more faster to deploy packages?

My simple idea is that if synchronize is using echoing style deployment, the performance will be better.

If these are packages, how about setting up a package manager and use a local mirror?

(I guess the first question is what kind of packages?)
