Get Your Data to Glass 180x Quicker: How to Setup Clusterize.js with Rails and Coffeescript

Here’s the situation: Your amazing developer team has rocked your world with caching and other optimizations to get data from your client’s Rails server over to the users’ browsers. Your monitoring shows requests that were taking a whole 80-90 seconds to serve are now only taking 1500ms (and all that time is actually spent transferring megabytes of html to the browser, actual data retrieval is ~10ms). These numbers come from a recent project I did for a client with production data. Now, to tackle the last piece of speeding it up… Chrome browser is taking MINUTES (6 minutes, actually) to fully build and render the page after it’s received the data. 100% unacceptable. Time to drop in some asynchronous data transferral and a specialized js library to keep things snappy client side!
