Backend: Limitation on Throughput

[PoojaGidaveer]

Performance Tests triggered on backend application on Initial HomePage - API - /events, /nodes

Inferences-

1. Started with 1 and scaled till 4 instances of the backend and max Throughput that we could achieve was 600req/s.
2. Comparison Tests on Apiserver gave the throughput more than 3k req/s
3. Apiserver can process requests upto 4kreq/s where as same 4 instances of backend can process max of 600req/s
4. More details can be found here- https://github.tools.sap/engsrvperformance/Kyma-Performance/tree/main/docs/Initial_HomePage_Tests

Limitation Backend is limited to 600req/s

Expected Behaviour Backend should give throughput similar to apiserver requests
