Performance. Reloaded.

We also show that with Mio, McNettle (an SDN controller written in Haskell) can scale effectively to 40+ cores, reach a thoroughput of over 20 million new requests per second on a single machine, and hence become the fastest of all existing SDN controllers.[1]

The new IO Manager in GHC 7.8 improves realistic web server throughput by over 6.5x and expected response time by 5.7x with room to grow.[2]


Digestive Functors

Form processing has never been better. A library based on Formlets, Digestive Functors enables you to validate and render your forms, including validating straight JSON requests.

<form action="/tweet" method="POST" enctype="application/x-www-form-urlencoded">

    <label for="tweet.username">Username: </label>
    <input type="text" id="tweet.username" name="tweet.username" value="">

    <label for="tweet.timestamp">Timestamp: </label>
    <input type="number" min="0" step="1" pattern="\d+" id="tweet.timestamp" name="tweet.timestamp" value="">

    <label for="tweet.content">Content: </label>
    <textarea id="tweet.content" name="tweet.content"></textarea>

    <input value="Submit" type="submit">
