Hi, zeng,xiaoxiao
some questions about your test case `test_perf_multiprocess_performance`
*. self.dut.kill_all() is used to kill dpdk revelant process, your test case hasn't run any dpdk process before it.
What's your target?
*. You use self.dut.new_session() to create new session in a for loop, but you haven't close these sessions. And this suite
has created one `session_secondary` session in set_up_all method, why you want to create new one?
*. When you run symmetric_mp, you haven't run server process, is it the test plan required?
*. After you boot up first symmetric_mp, you haven't close it and run other one, is it the test plan required?
*. Could you update this test case's test plan at the same time?
