Hey, author here! - Request rate is pretty low on average and peaks at around 15 requests/second. That's nothing really and it would probably take 100x or more request rate before I saw any kind of CPU bottlenecking or similar; my upload would probably bottleneck first. The biggest resource usage on the server comes from some expensive database queries made by some of my applications. - I'd definitely be down to use that kind of CPU but it wasn't available at the price point I wanted. Most of my stuff isn't CPU-bound anyway. - I used to self-host my own mailserver and webmail, but to be honest it was a disaster. Even after spending tons of time configuring reverse DNS, DMARC, SKIN, SPF, and the other list of arcane and specialized stuff you need, I still had tons of issues with mail I sent going to spam. I gave up and pay Google to host my mail for my own domains now. - I really haven't done much tuning. MySQL/MariaDB is the DB that gets the most load and its settings are most default. I have put a lot of effort into profiling my apps' query patterns and making sure proper indexes and schemas are in place, though.
