Problem with "Safari" web content(caching)?

Question

safari

Good evening. Tell me, please, who in system monitoring when running Safari and several tabs in memory appear several processes called - Web content "Safari" (caching)?
What is it and what are they responsible for? They just load the system. Thank you in advance.

Answer 1

These are the processes responsible for caching web content ... I don’t know what you expected to get in response)
This is a poppy, they don’t load anything except free memory, or do you basically need to see that there is free memory?)
