Question where can I learn more about apache, nginx, plesk performance

[larryk]

hello,
I'm trying to learn more, so i can get answer to questions like this:

1) if a website is wordpress, then you should have these settings ____ [what settings] _____ on the PHP settings page and the apache & nginx settings page in Plesk

2) if a website is only static content (no php, scripts, etc), then you should have these settings ____ [what settings] _____ on the PHP settings page and the apache & nginx settings page in Plesk

3) and other related/similar questions


IgorG provided me this:
https://docs.plesk.com/en-US/17.0/a...che-web-server-linux/apache-with-nginx.70837/
=== which is awesome!

http://php-fpm.org/about/
=== which is a little over my head, understanding

I know I can read the field text on the setting pages, but most of the time, it doesn't explain WHY or WHAT THE OPTION means? at least to me it doesn't.

So looking to understand how the settings effect my server, plesk and the site.

thanks!

PS. i'm moving from apache only 11.5 to 12.5 with nginx and apache

feeling stuck
but started testing various things on new server:

1) on wordpress site...
I did nothing, but site seemed to work perfectly on both:
FPM by nginx
and
FPM by apache
==> IS THAT POSSIBLE? I would have thought I had to do something with directives?

2) I was watching the real-time log monitoring and editing/viewing Wordpress pages...
everything was nginx? I thought apache did some page serving on a WP site?

3) I saw this error:
Access to the script '/var/www/vhosts/domain.com/httpdocs/testdir' has been denied (see security.limit_extensions)" while reading response header from upstream

what is "security.limit_extensions" ?


I found this, which look VERY good... but wonder if the info is good/valid for plesk?
