2 weeks ago this hits me especially strongly this morning. While a native solution would be better, maybe it can be done outside nix with a correct ssh configuration ? something like
controlmaster auto
controlpath /tmp/ssh-%r@%h:%p

Is your feature request related to a problem? Please describe.
Currently when doing remote builds, I see a lot of
connecting to <hostname>, which can be painfully slow when the remote is in another network, or when the builds are serialized, such as when doing IFD. Deep changes to config files, such as a small configuration change in a NixOS generation may also be particularly affected by this latency, unless we use or advance knowledge about the dependency graph in that case (don't think we do, but also not sure).Describe the solution you'd like
Have a connection pool for each of the builders.
Describe alternatives you've considered
Use an SSH master connection instead of a pool. I don't think we should force use of this feature though; it is more fragile and it complicates the user's configurations.
