Hi,

well with 200 nodes at a 30 minute interval, you should be fine. The
4*1800 CPU seconds that are available should be plenty for this node
count, as long as compile times don't rise to ~ 40 seconds.

Do the PuppetDB errors coincide with the overly long compiler runs?

FWIW, the read timeout does not feel like a performance issue to me, but
rather like a transient connectivity issue (packet loss?). This is just
a shot in the dark though - I have next to no experience operating a
PuppetDB instance.

Are the overlong compiler runs always exactly 120 seconds above the norm?

Thanks,
Felix
