Darius Ski created RF-12652: ------------------------------- Summary: Improve ScriptUtils performance by doing early preallocation in String encode path Key: RF-12652 URL: https://issues.jboss.org/browse/RF-12652 Project: RichFaces Issue Type: Enhancement Security Level: Public (Everyone can see) Components: core Affects Versions: 4.3.0.M2 Reporter: Darius Ski Priority: Minor In ScriptUtils.toScript(Object obj) method there is allocation of StringBuilder with default size (of 16bytes). When large sized strings are passed to this method ( for example in partial rendering user bean returns a String with custom JSON ), method incurs penalty due to reallocations ( both in GC pressure and CPU use). The preallocation size could be set to 1.6-2 of initial size, cause we know that String is getting escaped and inflated by both normal (*2) and unicode escapes ( \u00XX style * 6). -- This message is automatically generated by JIRA.
