Performance differences between Java framework and .NET framework

In terms of high-concurrency request processing, .NET ASP.NET Core Web API has better performance than Java Spring MVC. The reasons include: AOT early compilation, which reduces startup time; more refined memory management, where developers are responsible for allocating and releasing objects. Memory.

Performance difference between Java framework and .NET framework

Both Java and .NET are powerful application development frameworks. Popular among both businesses and individual developers. However, due to differences in their underlying architecture, there are some differences in performance.

Architectural Differences

• Java: Based on the Java Virtual Machine (JVM), which compiles Java bytecode into platform-independent code.
• .NET: Based on the Common Language Runtime (CLR), which compiles Intermediate Language (IL) code just-in-time (JIT) into machine code.

Memory Management

• Java: Automatically manages memory using a garbage collector, meaning the programmer does not need to explicitly Free up memory.
• .NET: Using a reference-counted garbage collector, it is the developer's responsibility to manage memory and reduce the reference count to zero when allocating memory for an object and freeing it.

JIT vs AOT compilation

• Java: JIT compilation compiles bytecode into machine code at runtime, This provides better performance but increases startup time.
• .NET: Use AOT (ahead of time) compilation to compile the IL code into machine code before running the application, which reduces startup time but may reduce performance.

Practical case

The following is a practical case that measures the performance of Java Spring MVC and .NET ASP.NET Core Web API framework in processing HTTP requests.

Test environment

• CPU: Intel Core i7-11700K
• Memory: 32GB DDR4
• Operating system: Windows 10 Professional

Test setup

• Load testing using JMeter
• 1000 concurrent users
• 1000 Requests

Test results

##Java Spring MVC128781.NET ASP.NET Core971031

Framework	Response time (milliseconds)	Transactions per second (TPS)

##Conclusion

It can be seen from the test results that the .NET ASP.NET Core Web API framework has higher performance than Java Spring MVC when handling high concurrent requests. This is due to its AOT compilation and more granular memory management. However, Java Spring MVC offers better portability and a richer ecosystem. Choosing the most appropriate framework depends on the performance requirements of the specific application and developer preferences.
