Performance improvement of critical code execution

A method for improving the performance of critical code execution, said method comprising:

• compiling and linking source code into a set of dynamic link libraries (DLLs), the source code including critical functions and non-critical functions, the DLLs including executable code, the critical functions corresponding to critical code in the executable code;
• optimizing the executable code by scanning the instruction stream of the DLLs and in-lining the critical code;
• generating a single prolog and a single epilog for the in-lined critical code;
• creating a single optimized DLL containing the in-lined critical code;
• and
• loading the optimized DLL into a reserved memory space.

An apparatus for improving the performance of critical code execution, said apparatus comprising:

• means for labeling portions of source code containing critical functions for which execution performance is to be improved;
• means for scanning the source code prior to compilation to locate the labeled portions containing the critical functions;
• means for configuring a links or to store all of the labeled portions containing the critical functions into an Executable and Linking Format (“ELF”) section header;
• means for compiling and linking the source code including the labeled portions into dynamic linked libraries (DLLs) using said linker;
• and
• means for loading the DLLs, including means for relocating the ELF section header at run-time into a specific memory space reserved for the critical functions.
