While there is a very complete Satellite 6.13 Performance tuning guide, I always struggle to find these parameters whenever I happen to change the CPU and RAM resources when Satellite is configured as a Virtual Machine.
Usually I care about tunning two things:
a) The number of Puma workers (helps with Satellite WebUI responsiveness and with the number of dynflow tasks it can handle)
b) The number of pulp workers so I can synchronize more repositories in parallel.
To tune this, in a 16 vCPU machine, I would use something like:
satellite-installer \ --foreman-foreman-service-puma-workers=8 \ --foreman-foreman-service-puma-threads-min=16 \ --foreman-foreman-service-puma-threads-max=16 \ --foreman-proxy-content-pulpcore-worker-count=8
