Thank you for the samples.

This remains of general interest, so I'll continue to cross post to the list.

It looks like most of the time is spent resolving the host names of the various hosts. I would take a guess that your DNS environment is configured such that hosts are not assigned host names or that there is potentially a configuration issue that is causing resolution to be delayed. Note that this can also impact the use of IP addresses in that certain API will sometimes decide it needs to do a reverse lookup to determine hostname (even if never used in the calling API).

If that is the case, then try configuring a static set of build hosts where the host names are the bonjour names of the remote hosts. I.e. "officeg5.local.". That sometimes improves the lookup times considerably.

Sometimes. DNS lookups can be a bit of a non-linear debugging and configuration experience.
