When you purchase a permanent license for the Web Performance Load Tester™ you get the ability to simulate a certain number of users, regardless of how many computers are on the back end, or how many computers it takes to generate the test users. Permanent licenses do not expire.
The Web Performance Load Tester™ consists of two separate programs, a "controller", the user interface which runs the test, and "load generating engines" which generate the virtual users. The load generating engines can be installed on any number of computers as needed to generate the licensed number of virtual users, but only one user at a time per license is allowed to generate a test. For example, two copies of a 500 virtual user license can not be run at the same time to simulate 1000 virtual users, but a single user could utilize a dozen different computers to generate 500 virtual users.
The Web Performance Load Tester™ software can be purchased with either a permanent or temporary license depending on your needs.
The license may only be installed on a single computer for use by a single person. Once the license is installed it can be moved to another computer by first deactivating the license, uninstalling the license, and the re-activating the license on a new computer.
Rather than purchase a permanent license, Web Performance Load Tester™ can be rented by the week or by the month. Because of the time limitation a temporary license comes with priority email and phone support. In all other respects, the licensing works exactly as a permanent license.
For more information please read the complete license document.
The license is for the total number of virtual users regardless of the number of computers being involved. The software is designed to collate the data from multiple engines into the test results and thus circumventing the license manager results in inaccurate test results.
The license holder purchases the permanent rights to execute the purchased program with a one time payment.
Every attempt has been made to provide a realistic view of the software's capabilities. Due to the wide differences in computing power between different models, we can not guarantee a particular hardware platform will generate the required number of virtual users.
This is not usually an issue because of the ability to utilize the power of multiple computers to generate tests. More information can be found in the hardware requirements and manual. The maximum number of virtual users that can be generated by a single computer is five hundred.
Increasing the number of virtual users costs the difference between the two licenses. So, if you purchased a 100 virtual user license for $1,995, and the 200 virtual user license is $2,995, you'd pay the difference, or $1,000. If you are a Premium Support customer, the concept is the same, only with the price of the support contract figured into the calculation.
The license is good for the length of the rental period, which starts at the time the software is purchased. The free version of the software is fully capable of creating test cases, so we recommend using that to make sure the test cases are working before buying a temporary license.
The software is licensed to generate the specified number of virtual users for a single website at one time. Multiple users can not use the software at the same time.
