The reason your site is taking long to load is because you have multiple >1MB assets. Open up the Chrome inspector and look at the network tab. You're loading 7.7MB, 7.3MB of which are images. There are two gifs that are over 2MB in size. You should reduce the size of them to 200KB at most, and also consider delaying loading images that are below the initial viewport until the user needs to see them. I also recommend compressing all of your jpg's and using a tool like ImageOptim to strip out any extraneous data.

Just deployed a new version of the app with optimized images. Thanks so much for the thorough, constructive feedback.

It cost me more than 30 seconds to load your website at the first time.

thanks for letting me know - is it better now? I just enabled oplog.

I just tried. The page was still empty 1 minute later. I had to stop loading and refresh it. This time, it loaded quickly.

Unable to connect to any application instances.

yeah this is the mongoDB gridFS bug that keeps crashing my website.

same reaction as other commenter when I visited your site. super slow to load.
