It's obviously more than that but also, you can have any type or make of db engine if you can't fucking configure it to handle a load like this without regular downtime. Maybe they lack rdbms expertise so nosql would be better for them? Who knows. Though I guess replacing the db backend would require a huge rewrite. It's as if the code couldn't really scale to the task at hand.

I bet you use nhentai.

The database was not the limiting factor. The hardware was. We haven't gone below our peak in February at any point in April, the lockdown really fucked our """future proofing""".
