> 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!
