.Net Tips – use [field:NonSerialized] to stop serializing your event handlers

In C#, when you define an event in your class, e.g.: the event handlers will be serialized along with other properties, etc. This is because under the hood, the compiler translates your event into the following, as can be seen through JetBrain’s dotPeek decompiler: Since the generated EventHandler is not marked with the [NonSerialized] attribute …

Performance Test – Binary serializers Part II

.Net, C#, Performance, Programming, SimpleSpeedTester

Note: don’t forget to check out the Benchmarks page to see the latest round up of binary and JSON serializers. A little while ago I put together a quick performance test comparing the BCL’s BinaryFormatter with that of Marc Gravell‘s protobuf-net library (.Net implementation of Google’s protocol buffer format). You can read more about my …

Performance Test – SortedDictionary vs Dictionary vs Map vs Array

.Net, C#, F#, Functional Programming, Performance, Programming

I stumbled upon this interesting question on StackOverflow today, Jon Harrop’s answer mentions a significant overhead in adding and iterating over a SortedDictionary and Map compared to using simple arrays. Thinking about it, this makes sense, the SortedDictionary class sorts its constituent key-value pairs by key, which will naturally incur some performance overhead. F#’s Map …

Performance Test – JSON serializers Part II

.Net, C#, Performance, Programming

Note: Don’t forget to check out Benchmarks page to see the latest round up of binary and JSON serializers. Follow on from my previous test which showed that the ServiceStack.Text JSON serializer was the top dog in town, I came across a little library called fastJson on codeplex so naturally I had to test it …

The cost of throwing exceptions

.Net, C#, Performance, Programming

After reading Ayende‘s post today, it got me thinking, just exactly what’s the cost of a try/catch block and more importantly what’s the cost of throwing exceptions. Like Ken Egozi mentioned in the comments, I too believe the test was unfair as the try/catch block was applied to the top level code as opposed to …

Nancy self hosting

.Net, C#, Nancy, Programming

One of the great thing about Nancy is that you can host it in pretty much everywhere, and that includes inside a console app! The documentations seems to be missing the self-hosting option however, but it’s easy and only takes a minute. First, create a console app and get the Nancy.Hosting.Self package from NuGet: Then …

Integrating Nancy with protobuf-net

.Net, C#, Nancy, Programming, protobuf

Over the last couple of days I’ve been playing around with Nancy, one of a number of micro web frameworks now available for the .Net platform. You can read more about Nancy on their github readme page but in short it’s an ultra lightweight, easily extensible framework that lets you run a HTTP web server …

Performance Test – BinaryFormatter vs Protobuf-Net

.Net, C#, Performance, Programming, SimpleSpeedTester

Note: don’t forget to check out the Benchmarks page to see the latest round up of binary and JSON serializers. When working with the BinaryFormatter class frequently, one of the things you notice is that it is really damn inefficient… both in terms of speed as well as the payload (the size of the serialized …

SimpleSpeedTester

.Net, C#, Performance, Programming, SimpleSpeedTester

Since I do a fair bit of performance tests on random things that pique my interest, it’s only natural that I should make the task of carrying out these tests easier for myself, so over the weekend I put together a simple, no frills framework to do just that! The SimpleSpeedTester project is intended to …

Performance Test – JSON serializers

.Net, C#, Performance, Programming

NOTE: For an updated set of benchmarks, see the Benchmarks page. For those of you who have worked with JSON data in .Net you should be familiar with the DataContractJsonSerializer class and the JavaScriptSerializer class already. Both allow you to serialize/deserialize an object to and from a piece of string in JSON format, though there …
