I have a Siteground cloud server, and I know nothing about servers. It hosts 8 websites, although 3 of them have their own dedicated IP addresses and cPanels.
It's on a Linux server, but there's something w/ NGinx mixed in there. For instance, sometimes they have to restart NGinx for me ... some type of combo or something.
The basic details on the server are:
- 2 CPU cores
- 3 GB RAM
- 40 GB SSD storage space
- I'm paying about $90/month for this
If I go into my WHM, Service Status, it says this:
- Server Load: 0.69 (2 CPUs)
- 31.4% (987,744 of 3,145,728)
- Swap Used: 0.01% (268 of 2,097,152)
- Disk Information: 74% usage
They're all WordPress installations, and recently -- despite no major changes -- my administrative areas in all Siteground websites began lagging extremely slowly and eventually timing out.
The techs are usually good, but this guy just told me to purchase 2 additional cores; he said I didn't need to purchase additional storage space or an extra GB RAM.
They're basically low maintenance sites and not too heavy w/ traffic. USS Vision, WebPrezence LLC (SSLd), and then my nonprofit organization, National Center For Due Process (SSLd, and is the largest and most visited of any of the 8 websites.
As server experts, is it possible for anybody here to tell if this tech is correct? Will adding 2 CPUs help, so I don't get locked out of my FTP, cPanel, and back-end of my websites? Is it possible to tell with the little amount of information I'm knowledgeable enough to provide?
Or am I way off here and should I be doing something else, leery of the tech's advice?
Thank you for any guidance anybody can offer!
