The load tests you do on your website are a lot easier to complete when you have a company behind the scenes that is going to do most of the work for you. They need to know what kind of site you are running, and they will let you know how your site holds up once they do all their work. The work they do is testing the limits of your servers while monitoring them at the same time.
The first thing that the company does is figure out how they will access your site, and they learn what it is like when they are running your site and figuring out how it works. They will see how much capacity the server has, and they will let you know what can be done with your site after the tests are complete. Each site has its own attributes that the testing company needs to think about, and they will let you know what is possible after they do their tests. When you’re load testing, it’s also important to use proper tools. LoadRunner, LoadView, and Httperf are some tools that you can use.
They also want to let you know in a report how each test went. You see if things are improving, and they will let you know what can be done to improve on the last test. You have to know this or the site will never get any better, and you also have to know for a fact that you will have options that will work on your site. This is why you hire someone who is going to know what the industry says about these tests, and they can tell you what the next best step is. Anything that you learn about the site will help you stay operational in the future, and you will avoid the problems that a lot of people have that make their sites crash all the time.
The only thing you can do is to get load testing or stress testing on the site as much as you can, and then you will know what the site will do when you are working on it. You can figure out how much it can take before you need to upgrade.
