    Converting IPublishedContent to Dtos and performance

    Hi guys,

    I actually wrote the question and posted it on StackOverflow here:

    The issue I'm having is that converting IPublishedContent to a Dto is causing a massive slowdown in code execution and I'm wondering why? Is there a more sensible approach I could use here?

    Unless you have hundreds/thousands of properties on your "Job" object, I wouldn't expect that much of a slowdown.

    One idea would be that you may have a custom property value converter that is taking a very long time for some reason (e.g., maybe it's hitting the database). I have seen some inefficiencies when working with prevalues (e.g., for properties that are drop downs), as it seems Umbraco sometimes hits the database working working with those. If you have a very slow database connection, that could explain it.

    Ah Nicholas, you hit the nail on the head!

    I noticed I had a helper method further down that was indeed hitting the DB to query some member data.. which is of course pulled from the DB.


    EDIT: Just updated my member query and it's dropped from ~7 seconds to < 1 sec - hooray!

    If you want to try some more tests, I'd recommend leaving some properties off of your Job object. Maybe try just mapping a single property, or a subset of properties, and see what the speed differences are.
