Virtual Services with larger VSI size like 100MB/200MB/500MB, takes longer time to open it (3mins/5mins/10mins), make changes and save it, and deploy it.
Appending more transactions to VS will increase the time to open, make changes and deploy it.
All supported DevTest releases.
Here are few things to help resolve the issue:
. Have more memory on Workstation machine where the VSI is opened, like 16GB/32GB/ than 8GB.
. Create a new project in Workstation with the VS MAR file.
. Try increasing the memory of the Workstation by setting -Xms and -Xms with the same values (like 1024M/2048M/..)
If still facing issue, can capture the heap dumps with any JAVA tools at https://www.baeldung.com/java-heap-dump-capture. Heap dump should show what is causing more time?
