When trying to evaluate your web hosting performance and server speed, you should look closely at the distribution of website components in relation to how long they take to load. If your issue is caused by a server, you will see that non-cache website features offer a relatively even distribution when it comes to component load times. This might give an inaccurate picture of whatís going on, unless you are dealing with an exceptionally low time to first byte.
When a website has severe server issues, they become apparent when trying to access a website that the end-user has already cached. This is where you are going to see that the time to first byte duration takes a lot longer than it really should. In a number of instances, time to first byte is the primary component that leads to overall website latency. Of course, the best way for you to get a clear picture of everything that is going on is by doing an in-depth web hosting server speed test.
