I have a site indzara.com that continues to have issues with CPU and RAM usage spikes. 503 errors happened as a result and the site has tanked in Google search traffic lately.
I have spent a lot of money with 3 different developers to attempt to fix the issue. Still no success. Installing WPMUDEV is also a part of my journey to improve my site performance and reliability.
I have SiteGround as hosting provider and am on a Cloud plan with 2 CPU cores and 4GB RAM. I am noticing that the RAM usage spikes to close to 3GB around 10:45 am PST every day. It sometimes exceeds 4GB as well.
1. How can I find out what drives this specific daily usage every day?
2. For a site like mine with 150 blog posts, 20 product pages and 25 other pages, what should be the normal CPU and RAM usage? I get around 20K visitor sessions a month now.
3. When I look in File Manager, I see 1.2 GB of files (images, excel spreadsheets) in Uploads folder. Is that too much?
The database size is about 300MB. These are after several rounds of cleanup.
Any thoughts would be appreciated. I am not a developer. If I failed to provide any necessary info, please let me know.
Thanks for your time.
