> That means we transfer 55 TB data / month

this isn't a lot. Helps that site is mostly text data.

I know of a relatively small cloud security system that transfers petabytes/month to/from a handful of customers.

4 ingest pods, 8 pipeline pods, 7 time-series db servers, 2 sql servers

The amount of data transferred is meaningless to compare. SO is a relatively complex site with dynamic content and real-time features.

Compared to other similar sites like Reddit or Quora which are far slower yet running on more hardware, it shows what proper efficient architecture and code can do.

Reddit threads are also much hotter for writing and have O(thousands) of replies.

Sure Reddit has more write activity but I don't see the number of replies being such a big factor. SO questions have answers, comments, tags, related questions, and many other secondary data to load. Reddit is slow due to poor architecture and a terrible frontend.

Old Reddit isn't slow. It seems to mostly be the new frontend.

Old Reddit is still slow, but not too bad. Reddit's new software stack is... Atrocious.

I recalled that back in the days when the new Reddit has been rolled out, there were quite a few days that it's difficult to open in mobile browser. Now it's much better.
