I will be doing a webinar with the good folks of PostSharp on the 22nd March to talk about the use of AOP and AWS CloudWatch as a pseudo real-time performance monitoring tool (see high-level overview here). It’s a free webinar, it runs from 22nd March 3PM – 4PM GMT, the registration link is here. …
Note: don’t forget to check out the Benchmarks page to see the latest round up of binary and JSON serializers. Since my last round of benchmarks on binary serializers, there’s a new player in town – MessageShark, which at the time of this writing does not support serialization of fields, but offers comparable speed …
This is something I’ve mentioned in my recent AOP talks, and I think it’s worthy of a wider audience as it can be very useful to anyone who’s obsessed with performance as I am. At iwi, we take performance very seriously and are always looking to improve the performance of our applications. In order for …

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 …
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 …

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 …
In F#, you have the choice of using a struct or a record as a lightweight container for data. The similarities between the two are striking – both are immutable by default, neither can be inherited, and they both offer structural equality semantics by default too! However, there’s a key difference between them, their performance …
In my previous post on discriminated unions, I presented discriminated unions as an alternative to standard .Net classes to represent hierarchical data structures. However, in terms of data structure, discriminated unions share much more similarities with enums than they do classes – both allow you to define a set of named constants and associate some …
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 …
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 …
