Wanted to add my 2 cents based on experience working with client's WordPress site on GoDaddy's hosting.
Check what type of hosting plan you're on. GoDaddy still has some very old Linux hosting plans that are pretty useless for WordPress. They're older, but many people might be on them since they don't know any better.
The only way to fix performance issues with WordPress in this case, is to switch to Deluxe cPanel hosting (or if you pay more to WordPress hosting plan).
This requires GoDaddy support representative to create cPanel order for a dummy domain. For example, if your domain is example.com - cPanel hosting plan should be example1.com (or whatever). This allows you to migrate your site over without taking website down. Once you finish migration, you have to delete old hosting plan and wait for the system to update, and then change main domain in cpanel to the correct domain.
It's a hassle for sure. Migrating to a new hosting company is easier, and recommended. But, I did want to mention this in case anyone else stumbles on this thread.
