When you purchase a license for the Web Performance Suite™ 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.
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 use 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 Suite™ software can be purchased with either a single-seat or a floating license depending on your needs.
The simplest license is single-seat, which is tied to a specific computer at a time. 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.
A floating license can be installed on multiple computers, but can only be run on one computer at a time. Note that the floating license can only be shared among people in the same building. Employees in different physical locations must purchase a separate license.
Remember, if you wish to have multiple people use the program at the same time then additional licenses must be purchased.
For more information please read the complete license document.
The software is licensed to be used by a single person at a time. In other words, multiple users can not use the program at one time on a single license. If multiple users wish to run tests at the same time, multiple licenses must be purchased.
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.
An upgrade is where a user moves to a new version of the software where the major or minor version number changes. For example, if the customer purchased 2.1, moving to version 2.2 is considered an upgrade. Once the support privileges in either the basic or premium support packages have expired, the user must purchase an upgrade in order to obtain a new release. Since the price of upgrading later is the same as a Premium Maintenance/Support Contract, purchasing a Premium Maintenance/Support Contract provides the best value.
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.
