Shared hosting will not give you the data needed to truly find bottlenecks.
VPS hosting is different at every provider. Some areas available in WHM some are not depending on the provider. Some have boilerplate setups some are ok, some plain out makes zero reasoning. Did you buy a hosting plan for 1 year and find out after the 30 day period all goes haywire? Do you have a ongoing issue with amazon bots or other bad bot issues. Maybe you have shared hosting plan and cannot figure why running so slow. I do have some answer not at the surface level that most hosting providers support will give you as a temp fix. My experience from 20+ years support online are typically by level 0 or 1 they have little to no troubleshooting experience and go for the first answer they can find to get you off the chat to the next one happy feeling of a plan a. Which more likely a plan z. I am stating this is only my opinions and may be proven wrong in future. The gut is strong on this!!!
