Umbraco Model and DynamicNode overhead





Just a quick post to show something interesting I discovered with Umbraco 4.7.1.


These 3 if statements do the same thing. However the first 2 turn out to be 2-3 times more expensive in terms of execution time.


if (Model.title == null)
{}





if (Model.title is umbraco.MacroEngines.DynamicNull)
{}





var current = new DynamicNode(Model.Id);
if (current.GetProperty("title") != null)
{}




What's more, is that if you call AnscestorOrSelf() on Model vs current (my instantiated DynamicNode) there is a doubling of those results.

It seems that there is some extra overhead going on with Model.

Yet another issue with Umbraco that makes little sense. I will be glad when version 5 is done and they hopefully make these things clearer.

They could have used something like "GetModel" versus "GetCurrentModel" to make it more obvious.

Nicely done, and VERY interesting. Thanks for a great post. Sherlock Holmes himself would be impressed!
