Hi Bob,
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.
Thanks,
Prema
