VPE has a serious performance drawback for rather big pages
-----------------------------------------------------------

                 Key: JBIDE-9372
                 URL: https://issues.jboss.org/browse/JBIDE-9372
             Project: Tools (JBoss Tools)
          Issue Type: Enhancement
          Components: Visual Page Editor core, Visual Page Editor Templates
    Affects Versions: 3.3.0.M3
            Reporter: Vitali Yemialyanchyk
            Assignee: Yahor Radtsevich
            Priority: Minor

rather big pages - in general dev project this is normal page size...
My proposition for VPE developers pay attention to performance. This is example place to enhancement: 

VpeNodeInvocationHandler -> invoke -> for every get attribute call in VPE templates - call this:

ElService.getInstance().replaceElAndResources(this.pageContext, toReplace);

ElService -> replaceEl -> getAllResources - array creation and then 
ElService -> replaceEl -> replace - array sort

FOR EVERY sourceNode.getAttribute("...")
in function VpeAbstractTemplate -> public VpeCreationData create(VpePageContext pageContext, Node sourceNode, nsIDOMDocument visualDocument) {...}

array create and sort operations should be performed only one time!
