What are other ways to accelerate code execution besides JIT compilation?

In addition to JIT compilation, there are other ways to speed up code execution:

• Static compilation (AOT, Ahead-Of-Time) — compiling code into machine code before runtime, reducing overhead during execution.

• Compiler optimizations — such as function inlining, dead code elimination, loop optimization.

• Using specialized libraries and algorithms — for example, algorithms with lower complexity, data structures with fast access.

• Parallelism and multithreading — parallelizing tasks to utilize multiple CPU cores.

• Caching results — memoization to avoid repeated calculations.

• Using native libraries and JNI — calling high-performance C/C++ code from Java.

• Memory optimization — reducing allocations, using object pools.

• Profiling and bottleneck removal — identifying and optimizing "hot" code sections.

Each of these methods can be applied depending on the specific task and environment constraints.
