#### You're [probably] doing it wrong. AKA *"What you probably didn't know about connection pool sizing"*. Watch a video from the Oracle Real-world Performance group, and learn about why connection pools do not need to be sized as large as they often are. In fact, oversized connection pools have a clear and demonstrable *negative* impact on performance; a 50x difference in the case of the Oracle demonstration. [Read on to find out.](https://github.com/brettwooldridge/HikariCP/wiki/About-Pool-Sizing). - +

#### WIX Engineering Analysis - + We'd like to thank the guys over at WIX for the unsolicited and deep write-up about HikariCP on their [engineering blog](http://engineering.wix.com/2015/04/28/how-does-hikaricp-compare-to-other-connection-pools/). Take a look if you have time. - +
