A great set of performance tests for datareader,linq to sql, ef

Thursday, March 19 2009 - Data Access

I'm not saying great because it shows where EF shines in performance, but because the tests look interesting and thorough. Alex Konduforov goes past the typical "let's test performance" queries that just do select * from customers and looks at query performance from a lot of angles. In a powerpoint deck where he presents his results, he also gives some great overview highlights of what impacts performance in these technologies.

Thanks to Eric Nelson for the pointer to this.

I've embedded the deck here.

Thank you for the kind words, Julie! I am following your blog for a long time since you are one of the Entity Framework experts and I learned a lot from you :) And I am glad that this presentation were helpful to somebody else. Unfortunately my blog is in Russian so it won't be very interesting for English-speaking people (but you can try using Google translation feature if you like). Also, if anyone is interesting in the test app I wrote to get the results, you can find it here:http://code.google.com/p/data-access-orm-comparison/It's not in Russian, it's in C#, so it can be read easily :) The app is quite pluggable so you can create the provider for NHibernate, LLBLGen or something else and compare the results.
