We wish we could host every website on the Internet for $2.99 a month. The reality is some websites need more power to run than our basic plan can provide. Some websites even need a lot more power, like a VPS or dedicated server. The normal process is to start on the Easy or Pro plan and work your way up as your site grows to a dedicated server. Big websites can have 10-20 dedicated servers all linked together. Our system allows for seamless upgrades and there is no upgrade or downgrade fees.
If you are seeing CPU and RAM overloading in your Cpanel than you probably need to upgrade or optimize your site more.
Each plan has more power and a lot some cases just changing your website can make it run faster.
The best way to have a fast website is to not use MySQL or PHP. HTML5 websites are the fastest and use the least amount of power.
