One of the reasons for us to include VUH is that it is the industry standard to price load testing products, so that you can easily compare. Another reason is because VUH allows you to use Loadium extra flexibly, for instance, you don’t have execution limits with VUH.
The smallest interval is 15 minutes. For example a 1000 user test running for a 25-minute test would consume 500 VUHs.
To determine how many VUH you need, you should take your highest traffic as the basis and add an additional 10% traffic to that level, to stay in the safe zone and you can calculate VUH based on the formula above.
