Application Performance Evaluation on Different Compiler Optimizations

How to evaluate computer’s performance is an important issue for engineers in the area of computer, especially for those vendors. Under different compiler optimizations, the application on the same computer perform diversely. In this project, we investigate the impact of application performance with different compiler optimization levels. We choose the compiler, GCC, as our target compiler. With the SPEC CPU2006 benchmark, we evaluate several benchmarks performance when compiling those with different optimization levels. In addition, we employ the metric tools, GCOV, to fetch the numeric data. Through the tables and figures, we analyze the impact of application performance affected by optimization levels.
