+Test suite description
+======================
+
+This document is for dpdk unit test: memcpy performance auto test.
+For this suite, mainily aims to analysis the cache to cache memcpy
+performance after run the memcpy performance unit test.
+
+The performance data is divided into four parts. 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.
+
+perf data:
+** rte_memcpy() - memcpy perf. tests (C = compile-time constant) **

+ memcpy_perf_autotest
+ quit
+ performance data stored in memcpy_perf_auto.log file
+
+2. copy log file to current server
+3. analysis the data
