Where can I find data about VSE capacity on load tests ?
You can find some very valuable settings and recommendations at sample-performance-benchmarks-for-basic-service-virtualization. With regards to an optimum capacity setting for a single VS running on a VSE, a recommended value to start with is 2 x CPU Cores.
Do you have the same document for DevTest 8.1 ?
Unfortunately, I do not. Sorry.
Theorically, the maximun TPS that a VSE can support is <=10 for VSE Functional Testing Licenses. To increase that limit you need a VSE for Performance License.
For sure the Fisical Limit will be determined by the server resources.
Here is some generic information.
Capacity setting information can be found at https://docops.ca.com/devtest-solutions/10-1/en/installing/preinstallation/system-requirements#SystemRequirements-DevTestServerRequirements
if you have a VSE on 1 core, 2GB RAM machine a total of 256 VS threads can be specified but it will depend on overall system resource utilization. Sometime a VS can take more/less resources and you can specify the Capacity based on the resource utilization. A thread means the Capacity what you set for each VS.
As a best practice for a 1 core and 2 GB RAM per VSE machine, we can recommend 1 thread for functional and 6 threads for L&P as a starting points and capacity can be increased based on the system resources. For example: If you have 10 VS's deployed and only 2 VS's are used for load testing then you can set Capacity of the VS's as below:
. All the 8 VS's which are used for functional testing can have the Capacity=1 . Remaining 2 VS's can have Capacity set from >=6.
