Which is faster? Redis or Elastic

This is weird question. But I want to clear my confusion.
Currently, my app using elastic for displaying list. if i use Redis when user first time fetching data, will my performance is speed up?

Thanks in advance.

You will need to test this yourself, I don't think anyone here will give you a definitive answer otherwise.

I would exoect Redis to be faster than Elasticsearch as it does not offer the same flexibility and stores all data in memory.

What is the performence problem you are trying to solve?
