Summary
- Much performance degradation when we use less instance count for environment or instance type: .x2gd.large with less resources.
- During the tests Parameter CPU=0 improved performance for a several workflows, so this point we are going to investigate more in this ticket, like MSF_TC: mod search by auth query, MSF_TC: mod search by contributors, MSF_TC: mod search by title query and ULR_TC: Users loan Renewal Transaction.
No memory leaks, memory consumption was stable during all of the tests.
- Tests had 100% errors count for AIE_TC: Create Invoices, AIE_TC: Invoices Approve, AIE_TC: Paying Invoices, TC: Receiving-an-Order-Line, Unreceiving-a-Piece and Unreceiving-a-Piece Workflows because data was not regenerated.
