+Subject: [PATCH] qemu-nbd: make native as the default aio mode
+
+When the file system is dealing with multithreading concurrent writing to a file,
+the performance will be degraded because of the lock.
+At present, the default AIO mode of QEMU NBD is threads. In the case of large blocks,
+because IO is divided into small pieces and multiple queues, it will become multithreading
+concurrent writing the same file. Due to the file system, the performance will be greatly reduced.
+If you change to native mode, this problem will not exist.
