I recently reorganized the SimpleSpeedTester project’s structure so that it’s easier to add tests to both the Json and binary serializer benchmarks, and to run the tests is as easy as running the RunBenchmarks.fsx F# script and then choosing which benchmark you’d like to run and then kick back and wait for the results to …
First of all I’d like to offer my sincere apologies to those who have asked me to update my benchmark numbers following the release of Json.NET 5.0.6, it took me a long time to clear some of my backlogs and only just got around to it, sorry for the waiting! The good news is that, …
Just a quick note to say that I have updated the JSON serializers benchmark to use the latest Nuget versions of ServiceStack.Text, Json.Net and JsonFX. I have also included the JSON and BSON serializers from the MongoDB C# Driver in the test, and since BSON is a binary format I have included protobuf-net as a …
JSON serializers benchmark updated – including MongoDB Driver Read More »
Note: Don’t forget to check out Benchmarks page to see the latest round up of binary and JSON serializers. Following on from my previous test, I have now included JsonFx and as well as the Json.Net BSON serializer in the mix to see how they match up. The results (in milliseconds) as well as the …
After watching Gael’s recent SkillsMatter talk on multithreading I’ve put together some notes from a very educational talk: Hardware Cache Hierarchy Four levels of cache L1 (per core) – typically used for instructions L2 (per core) L3 (per die) DRAM (all processors) Data can be cached in multiple caches, and synchronization happens through an …

I have heard a few people argue that when it comes to performance critical code you should prefer arrays over other collections (such as F#’s lists) as it benefits from sequential reads (which is faster than seeks) and offers better memory locality. To test that theory somewhat, I wanted to see if there is any …

To find out if a string contains a piece of substring, here are three simple ways of going about it in C#, just to name a few: String.Contains String.IndexOf where the return value is >= 0 Regex.IsMatch Out of curiosity I wanted to see if there was any noticeable difference in the performance of each …
