"Economic advantage" can be hard to define but we'll try.
eValid is first and foremost a productivity tool.
The goal is to get more done with less time and effort and with better effect using eValid compared with other tools or approaches/solutions.
So the costs of your effort, your computer time, you team time, have to be weighted along with the costs of access (license or lease or subscription).
We don't think it's appropriate to get into pricing details here, but we know of one server loading solution that will run in the $20K to $100K for a solution that simulates 1000 Virtual Users (VUs), whereas eValid's costs are about 10% of that for 1000 Browser Users (BUs).
If you have been following this forum for long, a BU is an eValid playback emulating a real user -- hence the term "Browser Bser". The main point of a BU is that the server cannot tell it is NOT a real user out there on the client browser.
A virtual user or VU is an HTTP simulation of the traffic that a user generated at some time in the past. Because of the technology used in HTTP based playbacks, you never quite have the same realism you get with an eValid REAL browser based playback.
So, here the economic advantage is a combination of price, quality, and ease of use.
Oh, the $1/browser-hour phrase refers to the cost of sustaining one browser repeatedly running the same script for one hour. In the load-testing community, the $1/browser-hour cost has become something of a threshold: Above that and you're too expensive, and below that, well, you probably don't have a real BU.
