Speed is everything! And it certainly is at this web performance themed pre-event the night before the performance.now() conference: Link Rel Preload.

We're getting into theme with a night of lightning fast lightning talks (600sec max). At the end of the night you can battle against the experts of the field in our Beat The Champions quiz. There will also be plenty of time to socialise with fellow perfaholics.

This event will be held at Meet Berlage (a 5 min walk from the Amsterdam central station). There is limited space, so make sure you RSVP to reserve your seat.

Your hosts of the night will be Henri Helvetica from WebPageTest and Annie Sullivan from Google.

This event is brought to you by De Voorhoede, WebPageTest and Google.
