Hello everyone.
I have a very generic question which is more of something I've been wondering. It's not of importance. So, I'm used to doing something like this:
blabla.Parent()
or
blabla.first()
blabla.Ancestor('blibliblulu') blabla.Children blabla.Descendant('iWasOnceACowboy')
The question is, is that way of traversing up and down the tree killing performance?
If so, is there a better way of searching for nodes?
Thanks in advance for any replies.
Hi Harry
Querying with Descendants, DescendantsOrSelf is the worst traversing methods, avoid them.

Hi Harry,
Depends on your site actually. If you only have 100 content items using descendants won't hurt your perfomance that much.
But when you have 10000 content items this will become a bottle neck.
I did a talk on how to optimize umbraco for speed. And also showed several alternatives to descendants.

Also this article on the subject is interesting : https://skrift.io/articles/archive/testing-the-performance-of-querying-umbraco/
But in the bottom line i avoid the use of descendants. Even a greed xpath query will give you better performance

Exactly what I needed. Thanks so much!

Is traversing umbraco slow?
