Efficiency and capacity of load testing tools

by 4 comments

If you are looking for a load testing solution to check the performance of your web site, or to start using permanently in your web development process, you may need to analyze various characteristics of many tools before you make your choice. One of such characteristics is the efficiency.

If you want to test a web application used internally by your company staff, you may need to check that it supports, say, 100 concurrent user sessions.

This is not a very big load for any tool. You will hardly need more than one generating system to run such test.

The situation is completely different, if you need to stress test a popular internet portal. A load of 100,000 concurrent users can be a good check for it. […]

Load testing a mobile website for iPhone

While mobile devices are replacing PCs for almost all possible applications, the Internet is also changing to address this technology shift. On the other hand, despite the unbelievable progress in the performance characteristics of smartphones and handheld computers, they are doomed to stay different from PCs by one parameter: screen size.

That is why most web sites offer different content when they are visited from a mobile device.

Of course, this content is usually just a reduced version with a very similar functionality. However the implementation of the underlying web application can be different.

As a result, your web site can experience significantly different performance problems when it is accessed by multiple mobile users.

Stress testing a web site with 100,000+ virtual users

by 4 comments

It is not a typical load testing project when you need to create 100 thousand virtual users. More than half of all web load tests are conducted with just a thousand virtual users or less, because higher load is not actually anticipated on the target web site in production.

Note that we are not talking about the number of users per day or hour. Those are concurrent users working with the web site simultaneously, in parallel.

At the same time a huge load mentioned in the title of this article is not a fantasy.

Such tests are really required for web sites with growing audience and advanced client functionality. Imagine any web site that delivers customizable user-dependent content updating dynamically: stock quotes, online meetings and chats, monitoring tools, etc. […]

Creating a load test report

by 69 comments

One of the most common questions in load testing is how to create a good test report that you would be able to present to your manager or customer. This big question actually consists of many smaller ones. What to start with? How to create the right test? What load parameters should be applied? How to interpret the results? Which numbers to look at when you browse through a long report generated by a load testing tool?

I will hardly answer all these questions and present the complete methodology in one article. This would be a long story and… it would be too boring. I know that there is a 90% chance that you really need something more simple and ready to use right away. I will simply present an example of the load testing report. A typical one, if you want.
