First, I'd like to say I absolutely love dndbeyond. I really enjoy using the service and especially as a new player, it's made getting into the game much less daunting.  However, the site suffers quite a bit from a speed performance perspective. Pages take an unusually long time to load and it quickly becomes frustrating when jumping around the site, whether it be toggling between character sheets, class information, and spells or hopping around an adventure to look up various notes. I know there's a lot more tangible and exciting features you guys can be focusing on, but I want to highlight the importance of site performance from a user experience perspective. Given the vast majority of the site's content is farily static, you have the ability to implement a caching system like varnish that could really help with this.

Thanks again for making such a great product and I continue to look forward to watching it evolve.

An example: clicking on Warlock from the ToC of PHB takes a good 5-7 seconds to load and drop me down the page.

Thanks for such a quick response and looking into it. If it's helpful here's a screenshot of the performance summary:

briansw,

If you currently do not have a subscription, it's probably ad javascript exectuing that is slowing down the render completion. We are continually working with our ad networks to improve their javascript execution (and ours) to try to make more of the calls non-blocking. We will also be taking advantage of more geographic edge-caching next year as well. 

The other possibility is to use the mobile app once it's available, as you'll have all the resources locally on your device. You might want to check out our Developer Q&A stream on Twitch at 1PM Central today. I have a feeling BadEye might have some discussions about the mobile app. ;)
