Muitos aplicativos executam consultas predefinidas com par\u00e2metros diferentes repetidamente. Com a execu\u00e7\u00e3o preparada, os aplicativos podem reduzir o tempo necess\u00e1rio para analisar e compilar um plano de execu\u00e7\u00e3o para essas consultas. As execu\u00e7\u00f5es preparadas proporcionam grande economia na lat\u00eancia da consulta e nos ciclos de CPU necess\u00e1rios para executar a mesma consulta.

A melhoria na lat\u00eancia \u00e9 totalmente transparente para os aplicativos existentes e n\u00e3o exige que voc\u00ea altere seu aplicativo ou suas consultas se tiver os \u00edndices certos para cobrir a consulta!
