Is it correct to say so without gathering sufficient evidence from the SAP application and, for that matter, the network? What is the delta here and how do we understand what is contributing to that delta? It could be a SAP resource issue like work process, CPU, Extended Memory, Heap Memory, Database SQL performance issues, Network and so on. Immediately, one might possibly think the network is the bottleneck. You might have come across a situation where E2E performance, especially response times measured at the SAP GUI client end, is quite longer or slower, but processing time on the SAP application end is not that longer and not comparable to the response time measured at the SAP GUI side.

The number of tests required might depend on the scale of deployment, business modules deployed, integrations, data volumes, customizations, expected workloads, and so on. Though the SAP solutions are perhaps thoroughly tested, rigorous performance testing is needed to understand the operations behavior of SAP under heavy loads. The success of these business operations depends on the reliability of the SAP deployment. SAP offers one of the best ERP solutions for enterprise business critical operations.
