EST DETAIL: parameters: $1 = 't', $2 = 't', $3 = 't', $4 = 'Subnet::Ipv4', $5 = 't', $6 = 'Subnet::Ipv6', $7 = 't' Version-Release number of selected component (if applicable): satellite-6.3.0-21.0.beta.el7sat.noarch How reproducible: always Steps to Reproduce: 1. Run ReX on subset of your 30k subscribed hosts and specify that subset with search query just "container1000" (it is part of the hostname, matching 29 hosts in my case) Actual results: There is a query taking above 1 second (add "log_min_duration_statement = 1000" to /var/lib/pgsql/data/postgresql.conf and restart/reload to make PostgreSQL to log it) Expected results: Maybe there is a way how to optimize the query?
