Here's how to think about it:

- performance testing is done to see how long a particular operation takes. How long does it take to request a web page or write some data to the database? It's just an operation and a time.

- load testing is a measure of what happens to your performance metrics as you do a bunch of concurrent operations on the system. How long does it take to request that same web page when 100 other people are also requesting it? What about 1000 other people? Load testing builds on performance testing by looking at how performance changes as load increases.

- stress testing is simply identifying what happens to your system when it runs out of resources so you can try to come up with a failure plan.

But James, it's much more fun to imagine that the topic has not been settled already by the well-established conclusions of a previous generation of engineers. If we need to keep debating these definitions, that's fine with me.

But if the debate results in the same conclusion, facts or standard, then it should not honestly be considered as innovative.

i am completely agree with Kapil.There are 1000 testing books available book in the market. Every book has their own definitions.so i strictly follow ISTQB terms which is followed by almost 30 countries.
Let me know if you guys any questions.

This article is very nice to know the great difference between the Load testing and performance testing. We love LoadStorm and think it is the best load testing tool available because it is easy to use and the price is right.

hi praveen,
i totally agree with what you say about performance testing, but however i would like to add few more words to what you wrote about load testing and stress testing,
i would like to state load testing as - checking whether the system can handle the expected load as specified by the developers/expected by the client.
and stress testing is - checking the break point of the application, its like applying a load beyond what the application can handle to check how long the application works before it breaks down.

I have a slight objection in the conclusion given for Load testing and Performance testing by Mr. Scott.

Performance testing is merely the term used to define the Performance of any system, Its measurement is made by different aspects like Load, Volume, Stress etc.
Here Load testing refers to the rate of response of the system (Client or server) with n number of requests.

Volume testing refers to the rate of response of the sytem with increased volume of data.

Stress testing refers to the increased level of both load or volume.

I think this is the simplified definition for all terms which constitute the Performace of an application.

The IEEE and ACM have both settled on common definitions for performance, load and stress tests. The following are paraphrased: Performance is the category. Load is a test under a defined set of events for a period of time with an expected level of response. Stress is a contantly increasing load with a defined step interval until the system reaches a point of unacceptable response or total system failure.
