> In ScriptUtils.toScript(Object obj) method there is allocation of StringBuilder with default size (of 16 characters). 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).
