For hosting users, there are often cases of website overload, causing website performance to be slow or even inaccessible. Overload here has many causes, it is necessary to check whether it comes from CPU, RAM, MySQL, hardware or software problems.
Servers are just like normal computers, sometimes running slowly when there are many processes running. To avoid overloads like this, you can upgrade the hardware and system. Similar to hosting when overload occurs, the best solution is to upgrade the package above it or you can upgrade to a VPS service.
Apart from upgrading, there is a cheaper and more interesting option to try, which is to find the cause of website overload. If you've found it, all you have to do is find a way to resolve the overload.
