All depends on the type of interaction.

A high usage one, absolutely improve the time of it.

Loading the profile page? Isn't done often so not really worth it unless it's a known and vocal issue.

This is very true, but I think some of it has to do with expectations too. Editing a profile page is a complex thing, therefore people are more willing to put up with loading times on it, whereas checking out someone's profile is a simple task and the brain has already moved on, so any delay feels bad.
