Full Page Caching Warmer

If I have full page caching warmer why do I need section.io?
Do I need to turn off the warmer to use section?

Hi

You don’t need to turn off any crawler you may have been using to warm or “prime” your cache. Your site will continue to work with the cache warmer and section.io in place.

However, you may wish to turn the warmer off as cache priming is not generally considered best practice. Cache priming can consume unecessary resource filling the caches with site elements which may not be trafficked by your users. The best warmers of the cache are your real users who, by their normal behavior browsing the website, will fill the caches with the most relevant content - and for the least cost.
