An introduction to Load Testing

As some of you might know, apart from working for Voxbiblia, I'm also working for Gatorhole for a while. Gatorhole's a pretty cool company that has launched some really great products, and Load Impact is one of them!

Load Impact is a load testing tool that helps to gauge the performance of a website. To put it in very basic non-techy terms, what load testing does is that it simulates a certain number of users all logging into one application at the same time.

Take Facebook for example. It's slowwwwww. Especially when there are 50,000+ users logging in at the same time. So, the website (possibly) crashes and people get annoyed. Now if this happens too often, people get annoyed and leave - no matter how nice the site is. For online companies, this poses a very serious problem. That's where load testing comes in - it simulates users and helps the user to improve their website performance.

Load testing was previously a very expensive tool which required quite a bit of technical expertise to run and interpret. Now, I'm not a tech person (in fact people who know me probably say that I'm the one who messes up the script!), but Load Impact came up with an online load testing service that made running and interpreting a load test simple enough for a complete novice like me to understand :D Try load testing a site using the widget below, and you'll see exactly what I mean!



If you want to embed this in your blog as well, just copy and paste the code below:



I'll share more tidbits about load testing next time :P I'll put in some interesting stuff on load testing the cloud as well, which I hope will interest my CS3216 buddies :D
