I rebuilt the test cases based on your information, that is, each drive has only one thread with high pressure, there is a significant performance loss. I previously provided test data for a single drive with multi-threaded, which can achieve performance stable and CPU savings. Thanks for your data, I will reduce the cost of each IO and submit the next version. -- hexue
