Quick LINQ performance question.
I have a database with many many records and it’s used for a webshop.
All query logic and paging is done with LINQ, and it performs quite well.
This is, because the usual search for products contains one or more where clause, and that shortens my result set to a couple of hundred results at max.
But.. there is an option to list all products (when no search criteria is provided), and that query is slow.. real slow. Even though i’m just asking for a single page with .Skip(20).Take(10), it’s still slow because the total result is something like 140000 products. Is there a way to limit this (or all) query, so that the speed of the whole thing is kept okay?
I don’t want to force my customers to provide one or more criteria.. but on the other hand i have no problem with telling them that they can never find more than 2000 products.
Thanks for helping!

What you can do is to have Linq use stored procedure from the database.
In that case, it will be faster because it is the database engine who will do the work and return it to Linq; the database engine is made for that, and it is closer to data than Linq.
I suggest you give it a try and give us feedback
