[Performance] Benchmark

[YunaBraska]

Description

To measure the success, It's needed to compare Spring Boot Rest with ObjectMapper and Nano with the HttpService. Nano and Spring boot are not reactive but usually non-blocking.

Requirements:

Spring Boot

• Uses Object Mapper
• Uses Controller Advise
• Uses Spring Boot Security

Nano

• Test with and without LogQueue
• Use a reusable static method for user verification

TestMap 1

• Startup times should not be included in the tests.
• The Rest endpoint should be secured and only accessible when the authentication header value equals bearer mock token
• Test rests request with nested json and different types including parsing date or timestamps
• Every rest request should create a log entry in json
• The response should be a simple json with message and with timestamp and UUID
• Test with 10, 50, 100, 1000 concurrent requests

TestMap 2

• Use same setup from TestMap 1 but now with an invalid user
• The response should be a simple json with error message and with timestamp and UUID

• TestMap 3

• Use same setup from TestMap 1 but now trying to access an unknown endpoint
• The response should be a simple json with error message and with timestamp and UUID

TestMap 4

• Use same setup from TestMap 1 but now access an endpoint which throws internally an exception
• The response should be a simple json with exception and with timestamp and UUID

Benchmarks are not easily to do since virtualization still depends on the shared hardware limits and hosting a machine like I did with a Raspberry Pi depends on physical network layers like gateways, proxies, kernel port bind limits, etc. At the end, Spring Boot and Nano performed nearly equally with a huge difference in resource consumption. But Spring boot does pretty well from the response times, even it does a lot of more request handling. Spring boot probably has some caching mechanism.

@Kazim1101 we can review this, but for me the topic is done. It does not make sense to publish these tests when the metrics are too hard to understand like these from Gatling.
