I have wordpress hosted in sub domain just now learnt WP Super Cache and cdn need to know how garbage collection works if I set the timmer to 10 min will it clear all the cache in my client system and they come to my server for new content every 10 min , if I have 10k visitors then 10k traffic every 10 min is this how the process works?

If you clear your cache every 10 minutes, only the first visitor after the cache is invalidated will get served non-cached data. The other 9,999k will see the cached pages that first visitor generated for the next 10 minutes.
If you’re asking this question, you’re doing something wrong. Cache shouldn’t be cleared every 10 minutes.
