Hi daiyan, According to the code, the pipeline is actually running on thread_main, which is attached to core 0. The following loop is to update the information of the connection. Therefore, the usleep function does not result in a lower occupancy of core 0. rte_eal_mp_remote_launch( thread_main, NULL, SKIP_MAIN); /* Script */ if (app.script_name) cli_script_process(app.script_name, app.conn.msg_in_len_max, app.conn.msg_out_len_max); /* Dispatch loop */ for ( ; ; ) { conn_poll_for_conn(conn); conn_poll_for_msg(conn); } If you have any other questions, please contact me. Thanks Close this ticket. |
