Why modern software is slow

Yes, last part of performance tuning is relatively simple process as you described, but that's only because apps where performance matters are developed from the ground app with performance in mind, so entire architecture is designed in a way that supports performance.

Now try to take some React developer that has been working for years in completely different abstraction level, and help him design more performant code base.

You really think all you will talk about are cache misses?

no, but you can definitely talk about it.

i also had a chat with a C++ dev that created a "Database"-class abstraction for our MongoDB instance and implemented methods to access each field of every documents separately - didn't care about side-effects, didn't know about ACID transactions and didn't care.

finding a good abstraction that allows for performance tuning later on is hard, no matter the language, and react devs should make use of good abstractions as well.
