Redis is very fast, even if compared with first class citizen in NoSql world, like RaveDB; here an interesting benchmark post: Redis vs RavenDB – Benchmarks for .NET.
And there’s more: ServiceStack’s C# Redis Client (previously on
CodePlex Google Code) is an open source C# Redis client based on redis-sharp.
Here a good tutorial where to start, and here the NuGet package.
I hope to have the time to play a little bit with it in next days; I will report my experience here in my blog.
