CPU/RAM Consuming + Cache

Hello,

I have a website with thousands of articles: https://digitalcine.fr/
Every time I tested one of those Broken Link checker plugin in the past, it took several hours and was heavily consuming the CPU/RAM of the server.
And most of them did not even finished the scan because they end up being stuck.

I haven’t installed miniOrange Broken Link Checker | Finder yet but is it going to be the same hours long scanning and heavy CPU/RAM consuming as any other previous plugins I tested so far?

I also have a triple cache layer on my website:
– Redis Object Cache: https://fr.wordpress.org/plugins/redis-cache/
– WP Rocket cache plugin: https://wp-rocket.me/
– CDN Cache using BunnyCDN: https://bunny.net/

When you say “please try after clearing the cache it will definitely work” => https://wordpress.org/support/topic/really-slow-9/#post-14983850
Do you mean that every time you have to scan the website, you must clear the entire cache before (Redis + Cache + CDN)?

Thank you,
Stf.
