Figure 2: Login VSI Interface
Login VSI interface shows 190 virtual users enabled in end-user Quality of Experience testing.
During this test, two parameters were changed to simulate conditions in a VDI environment on a
real-world network.
One was the level of user activity generated by the Login VSI script for the ESXi load test.
Workloads classified as "medium" and "heavy" were imposed on the Horizon View infrastructure.
A medium workload consisted of opening five applications simultaneously (of seven available) at
a type rate of 160 ms per character. The applications were replayed in a loop. Approximately two
minutes of idle time was included to simulate the behavior of real-world users.
The seven applications were: Microsoft Outlook 2007/2010 (browse 10 messages), Internet
Explorer (one Website left open, two Websites browsed), Word 2007/2010 (one instance to
measure response time and one instance to review and edit a document), Bullzip PDF Printer
and Acrobat Reader, Excel 2007/2010 (open a large spreadsheet), PowerPoint 2007/2010
(review and edit a presentation) and 7Zip.
A heavy workload provided a greater challenge to memory and CPU consumption because more
applications ran in the background. Eight applications ran simultaneously; the type rate was 130
ms per character; and the idle time was only 40 seconds.
The second parameter was desktop resolution, which assessed network utilization during testing.
"High resolution" was Full HD, 1080p, with p referring to the numbers of vertical lines displayed
on the screen. "Low resolution" was XGA (Extended Graphics Array), a high-resolution video
display mode that provides screen pixel resolution of 1,024 x 768 in 256 colors or 640 x 480 in
high (16-bit) color.
