> The latest HDDS-4454 has poor write performance. And there will be a lot of
> writing failures. (I tested 200 concurrent write threads, 128MB per file)

> In HDDS-5851, [putBlocks are required every 4
> chunks|https://github.com/apache/ozone/commit/89a12ad0331339ee364a59031eeeceed73add656#diff-64d9809fa04e72e1f2c0332c0f4afe04773d92188279cc7bde422a06c65305a5R280],
> which may affect performance. Originally we only did putBlock once after we
> wrote the whole block. So let's change the default here and try to keep
> putBlocks as low as possible. Tests found a 20% improvement in performance.
