I would not take a job where they ask such questions. Because in a business, it's almost always better to go with the cleanest and most maintainable solution, not the most performant. If I had been asked this question, my first response would be "Why does this need to be performant?" Junior developers blindly write code without knowing why something needs to be done a certain way.

Theres always pros and cons to take into consideration. Especially with large systems linked to the financial sector ;) That's why I checked how data variety changes finding times. This was a semi-cool experiment I think :)
