C# is attacking the #1 spot in the TechEmpower Plaintext benchmark.

Note that FASTER is not directly comparable to Redis, as FASTER is not just a cache. FASTER can index and access data larger than memory, as well as take consistent checkpoints for recovery, more like a persistent hash key-value store + cache combination. FASTER is multi-threaded and latch-free as well, which gives it very high performance on a single machine.

Some recently completed and ongoing/future work items on our roadmap can be found at https://microsoft.github.io/FASTER/roadmap. For instance, in FASTER C#, we recently added log compaction, support for deletes, inline variable-sized allocations, and a read cache. 

Devart T4 Editor is a powerful Visual Studio add-in for editing T4 templates with syntax highlighting, intellisense, code outlining, and all features of a first-class text editor add-in for Visual Studio. It provides very high performance and makes creating T4 templates easier and faster. As well as ensuring extremely high level of performance, it also speeds up and facilitates the creation of T4 templates. 

.Serving static content from a cookieless domain is a standard performance best practice 

RethinkDB is an open source NoSQL JSON database designed for web apps. Its main differentiator is that you can tell it to continuously push updated query results to applications in real time, rather than having your app poll for changes. 

As discussed in dotnet/runtime#33331 we're adding an analyzer to detect usage of platform-specific APIs. This analyzer requires a custom attribute applied to method, containing type, or assembly.
