In my new web hosting plan my Cpanel show I have 20 entry process only. I want to know if it is sufficient for a new WordPress website? If I hit the 20 Entry Processes max, is my whole site will be down?
It seems that your provider is just using the standard CloudLinux limits. Keep in mind an "Entry Process" only takes roughly a fraction of a second to complete, therefore most people get it confused with how many visitors they can have on their website. As you said it is a new website then yes 20 entry process is sufficient for your website.
