NGINX and WP Super Cache: Many php-fpm processes with active cache

Hello,

My problem:
on my webserver I see many “php-fpm” processes running ~50 processes at a time.
(Traffic is also high)

When i load a page on my website the page seems to be loaded from WP Super Cache path.
(I add a Header after “try_files” and the site source code has the WP Super Cache Comment at the end of the page)

My Questions:
Why are there many php-fpm processes?
(In my opinion everything should be loaded immediately from cache and therefore not many processes should be running)
Is the problem with WP Super Cache settings, nginx setting or something else?

Also i am not a professional and i am learning by doing.

Server: VPS, RAM 64 GB, 8 cores (Server itself should not be problem i think)
I am also using plesk

My nginx config looks like this:

#Permalink fix für Nginx Only + Check in cache for entry

# WP Super Cache rules.
# Designed to be included from a 'wordpress-ms-...' configuration file.

set $cache_uri $request_uri;

# POST requests and urls with a query string should always go to PHP
if ($request_method = POST) {
	set $cache_uri 'null cache';
}

if ($query_string != "") {
	set $cache_uri 'null cache';
}

# Don't cache uris containing the following segments
if ($request_uri ~* "(/wp-admin/|/xmlrpc.php|/wp-(app|cron|login|register|mail).php|wp-.*.php|/feed/|index.php|wp-comments-popup.php|wp-links-opml.php|wp-locations.php|sitemap(_index)?.xml|[a-z0-9_-]+-sitemap([0-9]+)?.xml)") {
	set $cache_uri 'null cache';
}

# Don't use the cache for logged in users or recent commenters
if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_logged_in") {
	set $cache_uri 'null cache';
}
