CPU: Enable More CPU Features for Improved Performance The Native Image build process has determined that your CPU supports more features, such as AES or LSE, than currently enabled. If you deploy your application on the same machine or a similar machine with support for the same CPU features, consider using -march=native at build time.

If you deploy your application on the same machine or a similar machine with support for the same CPU features, consider using -march=native at build time. This option allows the Graal compiler to use all CPU features available, which in turn can significantly improve the performance of your application.

x86 Options (Using the GNU Compiler Collection (GCC))

In some cases disabling it may improve performance because of improved scheduling and reduced dependencies. -maccumulate-outgoing-args ΒΆ If enabled, the maximum amount of space required for outgoing arguments is computed in the function prologue.

Specify `--march` in a Spring Boot Native Build - Stack Overflow

stackoverflow.com/questions/79737094/specify-march-in-a-spring-boot-native-build     2025-08-16T00:00:00.0000000
Use -march=compatibility for best compatibility, or -march=native for best performance if a native executable is deployed on the same machine or on a machine with the same CPU features.

Why is -march=native not enabled by default by compilers/IDEs?

stackoverflow.com/questions/52653025/why-is-march-native-not-enabled-by-default-by-compilers-ides
-march=native is a destructive flag. It makes the binary possible not compatible on a lot of hardware (basically any CPU that is not a direct descendent of the one used for compilation). It is simply too dangerous to enable this by default. Another important thing to consider is that -march=native 's main end use is optimization.

For most use cases, -H: options are sufficient and you typically do not need to distinguish between build-time and run-time configuration. For more information describing how to define and use these options, read the com.oracle.svm.core.option package documentation.

Check gcc or g++ Compiler Options Enabled by -march=native

lindevs.com/check-gcc-or-g-compiler-options-enabled-by-march-native     2025-04-25T00:00:00.0000000
When you're optimizing code for performance, especially in C or C++, using compiler options like -march=native can significantly boost speed by enabling all the SIMD instruction sets and CPU-specific optimizations available on the machine. This option tells the compiler to auto-detect the processor's architecture and use every feature it supports - like AVX2, and other instruction-level ...

GCC Machine-Dependent Options: Common Pitfalls and Solutions

You're compiling on one machine (let's say a newer Intel CPU) but trying to run the code on an older one. If you use a machine-dependent option like -march=native, the compiler will optimize for the machine it's currently on.
