This article will describe the differences in the workloads of 4.1 in comparison to 4.0. With the release of Login VSI 4.1 we included 4 new workloads. Three of these workloads are improved versions of the old Medium, Light and Heavy workloads. And the last one is a newly created workload.

Recommended: Simulating VDI Users - Introduction to Login VSI Workloads

From Light to Task worker

The Light workload was focussed mostly around Excel actions and Internet explorer actions. With the new Light workload we have made the workload more diverse and not focussed on one or two applications. We have included the following applications to the Task worker workload:

  • Outlook
  • Adobe
  • Copy and zip actions

The actual resource usage of the workload has also changed (compared from Light to Officeworker):

  • There is a Disk Write increase of approximately 18%
  • There is a Disk Read increase of approximately 52%
  • There is an IOPS increase of approximately 15%
  • There is a CPU usage increase of approximately 6%

The reason for the increase of resource usage is because we noticed that the original Light workload was too Light to be applicable as a simulated Light user. Also because the timer has changed the workload could increase its resource usage.

From Medium to Knowledge worker

Both the Medium and the Knowledge worker workloads have been designed as 2vCPU workloads. The Knowledge worker has been totally redesigned to support creating a 1vCPU workload called the office worker. The goal of the new Knowledge worker workload was to result in more stable and reliable VSImax numbers that are the same or very close to tests executed with Login VSI 4.0 Medium. The changes are:

  • Removed flash games
  • Over all balancing of the workload
  • Added copy and zip actions

The goal of the new Knowledge worker workload was to be more stable, more smooth and still generate the same amount of VSImax as the Medium. There are not, like the Light workload, applications added to increase or decrease the load.The actual resource usage of the workload has also changed (compared from Medium to Knowledge worker):

  • There is a Disk Write increase of approximately 7%
  • There is a Disk Read increase of approximately 3%
  • There is an IOPS increase of approximately 13%
  • There is a CPU usage increase of approximately 1%

From Heavy to Power worker

The Power worker is the new Heavy workload. In some scenario’s we discovered that the Heavy workload was not as heavy as we had designed. At some points (Storage) it was even less intensive as the Medium workload. This was not the desired result for a Heavy workload. The workload itself did not change in applications only in resources used. The changes are:

  • Added copy and zip actions
  • Balanced the CPU usage
  • Increased the amount of Disk Reads
  • Increased the amount of Disk Writes

The actual resource usage of the workload has been changed (compared from Heavy to Power worker)

  • There is a Disk Write increase of approximately 30%
  • There is a Disk Read increase of approximately 49%
  • There is an IOPS increase of approximately 54%
  • There is a CPU usage decrease of approximately 4%

Office worker

There is a new workload added that has no precursor, called the Office worker. This workload is based on the Knowledge worker workload. The main goal of the Office worker workload is to be deployed in environments that use only 1vCPU in their VM’s. We have included the following applications into the Office worker workload:

  • Outlook
  • Microsoft Internet explorer
  • Microsoft word
  • Adobe reader
  • Micrsoft Powerpoint
  • Microsoft Excel
  • Login VSI photo viewer
  • Doro PDF Writer

Overall the Officeworker workload has less resource usage in comparison to the Knowledgeworker workload. The difference was calculated in the same environment with VM’s that had 2vCPU’s.

  • There is no change in Disk Write
  • There is Disk Read decrease of approximately 11%
  • There is an IOPS decrease of approximately 13%
  • There is a CPU usage decrease of approximately 22%

Workload Resource Usage

We have created a table that contains the resource usage per workload. This will provide crucial information for advanced users. These metrics are measured from a single user / VM. All metrics are based on the Knowledge worker workload, this is our baseline in this table.
