Login VSI Workloads

From Login VSI Documentation

This section describes the default workloads that come with the Login VSI product. These new and improved workloads feature a new timer mechanism, which is executed multiple times within each workload, and determines the performance of the system during testing.

Note: For more information on the additional workloads that are available to download, please see the Workload Add-ons section.

Task Worker

This is a light workload, which runs fewer application and starts/stops them less frequently than the other workloads, resulting in lower CPU, RAM and IO usage.

The Task Worker workload uses the following applications:

  • Adobe Reader
  • Internet Explorer
  • MS Excel
  • MS Outlook
  • MS Word

It also uses native Windows apps (Notepad and 7-Zip) to complete the print and zip actions used by the workload meta functions.

Office Worker

The main goal of this workload is to be deployed in environments that only use 1(v)CPU. It is based on the Knowledge Worker workload, but has less resource usage in comparison. However, it is more intensive than the Task Worker workload.

The Office Worker workload uses the following applications:

  • Adobe Reader
  • Internet Explorer
  • MS Excel
  • MS Outlook
  • MS PowerPoint
  • MS Word
  • Photo Viewer

It also uses native Windows apps (Notepad and 7-Zip) to complete the print and zip actions used by the workload meta functions.

Knowledge Worker

The Knowledge Worker is designed for 2(v)CPU environments. This is a well-balanced intensive workload that stresses the system smoothly, resulting in higher CPU, RAM and IO usage.

The Knowledge Worker workload uses the following applications:

  • Adobe Reader
  • Freemind/Java
  • Internet Explorer
  • MS Excel
  • MS Outlook
  • MS PowerPoint
  • MS Word
  • Photo Viewer

It also uses native Windows apps (Notepad and 7-Zip) to complete the print and zip actions used by the workload meta functions.

Power Worker

The Power Worker is designed for 2(v)CPU+ environments. This is a very intensive workload that puts maximum stress on the system, resulting in very high CPU, RAM and IO usage.

Important: You must install the Pro Library to be able to use this workload.

The Power Worker workload uses the following applications:

  • Adobe Reader
  • Freemind/Java
  • Internet Explorer
  • MS Excel
  • MS Outlook
  • MS PowerPoint
  • MS Word
  • Photo Viewer
  • Simulated application install

For many of the applications in this workload, larger files and higher resolution media are used. It also uses native Windows apps (Notepad and 7-Zip) to complete the print and zip actions used by the workload meta functions.

Workload Resource Usage

We have created a table that contains the resource usage per workload, which provides crucial information for advanced users. These metrics are measured from a single user / VM, with all metrics based on the Knowledge Worker workload.

Note: These values will be different depending on the hardware used, virtual machine optimizations and user concurrency. The information provided below is only provided to help you understand how they behave relative to one another.
