Is necessary to compile linq queries in subsonic?

I'd like to know if it's necessary to compile linq queries to the subsonic entities?

For example would I'd need to compile the following linq query?

var comments = from a in All()
                           where a.ParentCommentId == ArticleCommentId
                           select a;

From stackoverflow

• Compiled queries are an optional optimization that allow you avoid parsing an expression tree multiple times. It's never required, but may be necessary to meet your performance requirements.

  romkyns : I should mention that the cost can be quite significant unexpectedly. Any place where a query is invoked in a loop may need either refactoring or compiling the queries in the loop. Otherwise a tiny innocent-looking query invoked a mere 10 times may suddenly give you a 0.5 second delay in the user interface.
