When visiting a site or using an app, we want action. Slow load pages, a click through to nowhere or being stuck with the never ending circle makes tempers fray. Is it too much to ask to want a smooth experience that doesn’t take an age and delivers satisfaction, not frustration?

Top performance testing tools

Your systems and software probably perform as they should on a normal day, but don’t be complacent. What about abnormal days and abnormal loads and stresses? How well do they cope then?

You have to know where bottlenecks and breaking points will appear when heavy traffic puts your systems under stress. To do this you need to use a performance testing tool specifically designed for load testing. If you’re not sure where to start, take a look at our blog on performance testing.

Hopefully your well planned launch campaign is a big success and your product is the talk of all the best blogs. Can your site handle the extra attention coming its way? Or as a growing e-commerce outlet, how will your software cope when the Sales start? Opportunities are lost each time a user is met by a crashed site or a broken link. If you can’t give them what they want, they’ll shift their attention to one of your competitors without giving you a second thought.

Here, we’ve pulled together a list of the market leaders and our own favourite performance testing tools for load testing, to help you to prepare your system for whatever life will throw at it. Most of these offer a free trial so you can try before choosing the best performance testing tool for your needs.
