DPDK allocator\nperformance is affected by EAL options, API used and, at least,\nallocation size. New autotest is intended to be run with different\nEAL options. It measures performance with a range of sizes\nfor dirrerent APIs: rte_malloc, rte_zmalloc, and rte_memzone_reserve.\n\nWork distribution between allocation and deallocation depends on EAL\noptions. The test prints both times and total time to ease comparison.\n\nMemory can be filled with zeroes at different points of allocation path,\nbut it always takes considerable fraction of overall timing. This is why\nthe test measures filling speed and prints how long clearing takes\nfor each size as a reference (for rte_memzone_reserve estimations\nare printed).\n\nSigned-off-by: Dmitry Kozlyuk <dkozlyuk@nvidia.com>\nReviewed-by: Viacheslav Ovsiienko <viacheslavo@nvidia.com>\n---\n app/test/meson.build | 2 +\n app/test/test_malloc_perf.c | 174 ++++++++++++++++++++++++++++++++++++\n 2 files changed, 176 insertions(+)\n create mode 100644 app/test/test_malloc_perf.c", "diff": "diff --git a/app/test/meson.build b/app/test/meson.build\nindex 344a609a4d..50cf2602a9 100644\n--- a/app/test/meson.build\n+++ b/app/test/meson.build\n@@ -88,6 +88,7 @@ test_sources = files(\n 'test_lpm6_perf.c',\n 'test_lpm_perf.c',\n 'test_malloc.c',\n+ 'test_malloc_perf.c',\n 'test_mbuf.c',\n 'test_member.c',\n 'test_member_perf.c',\n@@ -295,6 +296,7 @@ extra_test_names = [\n \n perf_test_names = [\n 'ring_perf_autotest',\n+ 'malloc_perf_autotest',\n 'mempool_perf_autotest',\n 'memcpy_perf_autotest',\n 'hash_perf_autotest',\ndiff --git a/app/test/test_malloc_perf.c b/app/test/test_malloc_perf.c\nnew file mode 100644\nindex 0000000000..9686fc8af5\n--- /dev/null\n+++ b/app/test/test_malloc_perf.c\n@@ -0,0 +1,174 @@\n+/* SPDX-License-Identifier: BSD-3-Clause\n+ * Copyright (c) 2021 NVIDIA Corporation & Affiliates\n+ */\n+\n+#include <inttypes.h>\n+#include <string.h>\n+#include <rte_cycles.h>\n+#include <rte_errno.h>\n+#include <rte_malloc.h>\n+#include <rte_memzone.h>\n+\n+#include \"test.h\"\n+\n+#define TEST_LOG(level, ...)
