Assuming you have defined a workload with a certain amount of virtual users and you have a pool of agents you can choose from. But when it comes to selecting agents, it is often hard to tell how many agents you need to execute the specified amount of virtual users. This is where Silk Performer's Evaluate Agent Capacity feature becomes useful. It will tell you, based on an evaluation run, how many virtual users a particular agent can handle.
In this blog article, we will discuss how the capacity is actually evaluated and on which criteria the resulting number is based on. Then we'll walk you through a real-world example and we'll try to find out how many agents we need to execute a load test with a certain amount of virtual users.
In Silk Performer 16.5, the whole pacing functionality has moved to the Workload Configuration dialog, where it now has its own dedicated tab. If you already have a good grasp of pacing, you'll also appreciate the enhanced user interface, which allows you to conveniently set up and manage your pacing settings. If you're not yet familiar with pacing, this blog article might be just the right opportunity for you to get started. We're going to explain the purpose of pacing, how it works, and we'll show you step by step how to set everything up in Silk Performer.
