Yes these were my biggest problem with this post; they don't spend the time to try and find out bottlenecks and when they finally do instead of investigating the WHY they're thinking about simply switching to yet another which is going to have the same issues if they're not using an optimal data model, etc.

This is unfortunately a very common problem-solving approach. I've seen devs upgrade jQuery because they're getting a 500 error from a PHP app. No relation to the problem - it's just flailing around in hopes something random works.
