ENC slows down puppet

Hello,

We have around 5k hosts.

With foreman ENC puppet becomes unresponsive.

Only this errors in the log:

Without puppet node classifier everything works find (we export to puppetdb)

Any suggestions? Thanks

Also, reports slow down puppet master.

I don’t see any issues on foreman backend servers - they’re not load and pretty fast.

Any suggestions?

Thank you
