Performance optimization
This information describes
guidelines for improving the performance of your XL C/C++ application.
Performance improvement can be achieved through coding, compiling,
and the runtime environment. The following topics discuss guidelines for these three areas:
- Improving program performance
- Using built-in functions to improve performance
- I/O Performance considerations
- Improving performance with compiler options
- Optimizing the system and Language Environment
- Balancing compilation time and application performance
- Stepping through optimized code using the dbx debugger utility
