The compiler's default optimizations, /O2 (-O2 on Linux*), generate very good code for all IA-32 architecture processors. In addition /Qipo (inter-procedural optimization or IPO, -ipo on Linux), /Qprof_use (profile-guided optimization or PGO, -prof_use on Linux), and /O3 (high-level loop/memory optimizations, -O3 on Linux) can add additional performance for many types of applications. The /Qax, /Qx (or -ax, -x on Linux) options generates some specialized code for specific Intel processors. This results in even better performance on specific Intel® processors for some types of applications, while continuing to deliver industry leading performance on other processors.
For more information on processor-specific optimizations, see Intel® compiler options for SSE generation and processor-specific optimizations.
