Send packet with packet generator with different packet size,includes [64, 128, 256, 512, 1024, 1518], check the throughput with below command:: - - testpmd>show port stats all - -4. Repeat the test with dequeue-zero-copy=0, compare the performance gains or degradation. For small packet, we may expect ~20% performance drop, but for big packet, we expect ~20% performance gains. diff --git a/tests/TestSuite_vhost_dequeue_zero_copy.py b/tests/TestSuite_vhost_dequeue_zero_copy.py deleted file mode 100644 index 0779edcb..00000000 --- a/tests/TestSuite_vhost_dequeue_zero_copy.py +++ /dev/null @@ -1,532 +0,0 @@ -# -# BSD LICENSE -# -# Copyright(c) <2019> Intel Corporation. -# All rights reserved. -# -# Redistribution and use in source and binary forms, with or without -# modification, are permitted provided that the following conditions -# are met: -# -# * Redistributions of source code must retain the above copyright -# notice, this list of conditions and the following disclaimer. -# * Redistributions in binary form must reproduce the above copyright -# notice, this list of conditions and the following disclaimer in -# the documentation and/or other materials provided with the -# distribution. -# * Neither the name of Intel Corporation nor the names of its -# contributors may be used to endorse or promote products derived -# from this software without specific prior written permission. -# -# THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS -# "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT -# LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR -# A PARTICULAR PURPOSE ARE DISCLAIMED.
