I’m not familiar with Haskell concurrency. The combination of green threads and large memory allocations due to immutable data structures sounds like it would be hard to implement a web server handling 10k+ concurrent requests on commodity hardware?

Btw. too bad author talks about microsecond guarantees usage but does not provide a link, that would be interesting reading.

> Warp is a high-performance HTTP server library written in Haskell, a purely functional programming language. Both Yesod, a web application framework, and mighty, an HTTP server, are implemented over Warp. According to our throughput benchmark, mighty provides performance on a par with nginx.
