Pierwszy artykuł z serii jak budować wydajniejsze zapytania przy użyciu Entity Frameworka. W tym artykule przedstawię informacje, które kroki przetwarzania zapytania przez Entity Framworka mogą być usprawnione.

I’ll describe a few patterns that enabled me to process 2 billions items per day using Azure Functions. Yes 2 billions items per day. The aim of this trial was not to check whether you can do it with Azure Functions. You can do it easily. The goal was to do it in a cost-aware and cost-wise manner, enabling fast processing with a small amount of money spent on this.

Performance! Jak dobrać odpowiedni typ danych do postawionego zadania. We wpisie analiza różnych typów kolekcji w kontekście budowania drzewa commitów.

A simple performance comparison between approaches encouraged by F# (immutability and functional programming) and C# (mutability and OOP). Which one would you choose?

Reading time ~4 minutes This post is an analysis of a very interesting optimization proposed by Nicholas Frechette in the comments under the previous post. He proposed to use one of the oldest tricks in performance cookbook - divide and conquer. Well, it did not turn out as I expected.Saga Before I go further here are some link to the previous posts on the problem of calculating similarities and then optimizing. This thread grew to a few post. Here are all of them:How I calculate similariti...

Reading time ~2 minutes This post was inspired by a discussion on Reddit that followed my previous post In this post, I will cover a suggestion by BelowAverageITGuy that cut down the total execution time by almost one hour. Saga Before I go further here are some link to the previous posts on the problem of calculating similarities and then optimizing it grew to few post.

Reading time ~6 minutes Last time I’ve shown how I’ve gone from 34 hours to 11. This time we go faster. To go faster I have to do less. The current implementation of Similarity iterates over one vector and checks if that ingredient exists in the second one. Since those vectors are sparse the chance of a miss is big. This means that I am losing computational power on iterating and calling TryGetValue. How to iterate only over the mutually owned ones and do it fast? Saga Before I go furth...

Attribute routing (RouteAttribute) is a quite handy feature of ASP.NET MVC. It allows you to have nice looking URLs that everybody has already accustomed to and your client surely loves it. Plus it hides your true controller/action structure which sometimes might be desirable. But there's one catch. As your web app gets bigger and bigger, attribute routing might have a negative performance impact on your WHOLE website.
