There's a distinct lack of Javascript, few (no?) images, and the CSS seems very light. That'll get you a long way right there.

[EDIT] for a similar "oh, I forgot the web could be this fast when we don't pile a ton of shit on top of it" experience, try Basic HTML gmail some time. Its full-page loads are (most of the time) much faster than AJAXy Gmail or Inbox. See also: craigslist.

I wonder what's the backend of this app. BuiltWith doesn't detect much.

Edit - I really like the simplicity of search box (no JS):

    <form class="search" action="/search" method="get">
         <input name="query" placeholder="Search" type="search" required>
         <button type="submit"><svg> ..search icon.. </svg></button>
    </form>

Flask for web framework, Elasticsearch for search. The speed might be due to the fact that there is no JS / images on the front end.

Just had a conversation last night about SQLAlchemy support of NoSQL dialects like. I bet you didn't use a Model layer. Right? Is there anything you want to share in that regards?

Seriously. It was so fast I was convinced it was precaching results as you type but it's not. Would love to read a write-up on this.

I thought you and the other comments were exaggerating, but you're actually not. This feels impossibly fast from a user perspective. I'd love to see a write-up of this as well.

How does https://whosmentoring.com compare? Albeit hosted in SG so may have more latency.

Never mind. The site loads now. I was a bit confused about the site. As in what kind of mentoring are the listed people providing. The HN link at the bottom helped getting a better picture: https://news.ycombinator.com/item?id=15148619

Sorry I haven't enabled s yet.
