A Question to Treehouse Staff

Quizzes on treehouse has become faster and more responsive. I would like to know how that happened. I have few real-time applications and sometimes websockets don't work properly send or receive the data or worse the application crashes from time to time. My web applications use socket.io and Heroku.

I've checked the frontend it seems you guys are using an additional service called PubNub. Is that the reason why quizzes are more 'responsive' now? and Could you guys briefly explain the details behind your socket infrastructure.

Hi Izel Nakri -

Well, it depends on your context. :) I don't know when you last tried quizzes, so I can't tell you exactly what's changed that might have made them faster.

We do make use of PubNub, but I'm pretty sure that's for code challenges and our notification system - for the quizzes it's all just AJAX (all we need to do is verify the student's answer and then load data for the next question, so we don't really need a socket connection for that).

Hope that helps.
