Well, that's pretty substantial for the remaining nodes. Say you're load-balancing 400 read-only connections across 5 standbys. I'd expect to do 80 connections each, not 400 connections each. That's a huge difference in the number of connections per server, and the number of active processes on the pgpool server. In that example, the difference is 2000 processes on the pgpool server vs. 400. 2000 processes is enough to degrade linux performance. --Josh _______________________________________________ Pgpool-general mailing list [email protected] http://pgfoundry.org/mailman/listinfo/pgpool-general
