Profiling is a pretty basic technique that is applicable to all software engineering. I'm not sure what a "normal" service is here, but I think we all have an obligation to understand what's happening in the systems we own.

Some people may believe that 100ms latency is acceptable for a CLI tool, but what if it could be 3ms? On some aesthetic level, it also feels good to be able to eliminate excess. Finally, you should learn it because you won't necessarily have that job forever.
