Each part has two +colums data for cache to cache performance. After extract the data, +compute the geomatric mean for each colum, and then let the second +geomatric divide the first goematric mean, then get the ratio of the +two geomatric means. + +if the ratio greater than 1, then the test got a great performance. + + +============= +Prerequisites +============= + +Test Case: memcpy_perf_analysis +=============================== + +1. run memcpy_perf unit test + ./x86_64-native-linuxapp-gcc/app/test -c f -n 1 + memcpy_perf_autotest + quit + performance data stored in memcpy_perf_auto.log file + +2. copy log file to current server +3. analysis the data ++--------------------+-----------------------+------------------+---------------------+ +| 32B Aligned(ticks) | 32B Aligned CT(ticks) | Unaligned(ticks) | Unaligned CT(ticks) | ++====================+=======================+==================+=====================+ +| 1.893 | 2.509 | 1.507 | 1.500 | ++--------------------+-----------------------+------------------+---------------------+ -- 1.9.3
