[infinispan-issues] [JBoss JIRA] (ISPN-4219) Concern about proposed configuration

Brett Wooldridge created ISPN-4219: -------------------------------------- Summary: Concern about proposed configuration Key: ISPN-4219 URL: https://issues.jboss.org/browse/ISPN-4219 Project: Infinispan Issue Type: Feature Request Components: Documentation-Core Reporter: Brett Wooldridge Assignee: Dan Berindei Priority: Minor I'm writing on behalf of the HikariCP project. We're thrilled to see HikariCP included as a configuration pool option for exoCR (though it would be great if it were the default): http://docs.jboss.org/exojcr/1.16.0-GA/developer/en-US/html/chapter-Kerne... Though we are concerned a bit about the example configuration given creating a pool of 600 connections. We have a short but concise write-up on connection pool sizing where we make a compelling argument that a connection pool larger than a few dozen connections -- even for workloads of 10k simultaneous users running 20k transactions per second -- causes degradation of performance: https://github.com/brettwooldridge/HikariCP/wiki/About-Pool-Sizing We would be pleased if you read it, and if you agree, adjust the pool size in your example configuration.
