DNS Management

Domain Registrars

domain registrar is normally the place where you purchased/obtained your domain
Your registrar could be a business that only does domain registration or even your web host itself.
whenever a request for a domain is made, the registrar is the first place that gets referenced for information.

Nameservers

they identify what set of servers any requests should reference in order to obtain a domain’s DNS records.
Your domain should have it’s nameservers pointed to wherever you are intending to manage your site’s DNS records.

General Tuning

Worker Processes and Worker Connections

nginx uses a fixed number of workers, each of which handles incoming requests. The general rule of thumb is that you should have one worker for each CPU-core your server contains.

You can count the CPUs available to your system by running:

$ grep ^processor /proc/cpuinfo | wc -l
