If you own a car, you probably know how fast it can drive. You may not use its upper limits a lot, but you know the numbers and the manufacturer tests them before putting it up for sale. If you own a Website, do you know how fast it can deliver the Web pages you have worked hard to publish?
Chances are you may not know the upper limits of your Website as well the upper limits of your car. However, is it important for you to know the numbers? It depends. If you are aiming for visitors measured in millions or sudden spikes in traffic when you have hot news revealed then you want to know the upper limits of your Website's speed and performance.
The good news is there are tools available to help you measure your Website's and server performance. Pylot is free and open source tool to test performance and scalability of Websites. JCrawler is also an open source stress testing application. You give it a set of starting Urls and off it goes. Jmeter is another open source desktop application to load test funcctional behavior which is valuable if your need to test frequent user behavior performed on your Website.
