The following table collects performance results for the double precision (64-bit) Linpack benchmark program in C using the native Sun C compiler, cc version 4.2, on Sun Solaris 2.5 and 2.6.
Three optimization levels are tested, and their relative performance is exhibited.
The lowest optimization level is -g, for debug compilation.
The second level is -O, for normal optimization.
The third, and last, level is -xO5 -dalign -xlibmil -xcg92, which selects maximal optimization, allows use of doubleword loads and stores, allows inlining of small procedures, and selects the code generator for SPARC Version 8 (1992), which provides integer multiply in hardware. For brevity, the column header in this case is abbreviated to just -O5.
To allow others to repeat these tests, the Makefile and linpackc.c files are available here.
