If it was slow for a small number of users, that is a fundamental design or operations flaw, not a scaling problem.
Nobody is saying that performance doesn't matter. But if it performs well with 100 users, you can worry about the performance with 10k users later. And if it doesn't perform well with 100 users, it doesn't matter if the scaling is O(logn) even O(1).
Performance under a sudden flood of users matters, but a lot less than day-to-day performance. And most of the criticism I see for sites dying is when they're serving static content with ideal O(1) scaling, but in a very unoptimized way.
