Your site's performance is bad, and you should feel bad
When you build a site with Drupal if you don't do it right your users are going to have a bad time. Drupal, like every CMS, when not properly tamed can be slow and use tons of bandwidth. It's 2015, I shouldn't have to explain to you why performance is important and why you should care about it.
Modules I'm using
- Entity Cache
- Advanced CSS/JS Aggregation
- ImageAPI Optimize Using this patch for TinyPNG
- SVG as Image (not standard module)
Module I've used or heard of and cannot completely give my stamp of approval
In a little over two hours configuring the modules listed above, I was able to gain large performance increases on a very simple site. File size dropped from 985KB to 382KB, speed from 6.67s to 299ms. This was all running locally so I wasn't even using things like Memcache or Varnish which I would suggest for any production site.
Please be a responsible developer or designer and make websites that perform, no one wants to wait for a site. You absolutely cannot overdue performance! Thanks for helping to make the world a better place.
