VDI Load Testing: When do I need an extra VSIshare?
Why do people perform load tests of their virtualized desktop environment? Most likely to get more insight in the performance and maximum capacity of their environment. In order for Login VSI to give you these test results we need data–lots of data. That’s why during a large-scale Login VSI test, logfiles are continuously sent to the VSIshare and sessions are also doing read actions on the files that are located in the VSIshare. This means that a lot of data is written to the VSIshare and sometimes your VSIshare can get overloaded. This can have a negative impact on your test because of 1. loss of test data and 2. timeouts during copy actions.
How to see if this happened during a test
The best way to find out if this is happening during your tests is to open the Analyzer and look at the VSImax v4 Scatter tab. The data is by default presented with response times in milliseconds on the Y-axis and the amount of sessions on the X-axis.
