>
> HDDS-1719 changed the default segment file size from 16KB to 1MB. It is still
> too small. We should change it to something like 64MB.
> HDDS-2683 set the buffer size to the same as the segment file size to avoid
> the buffer size being larger than the segment file size. We should allow the
> buffer size being smaller (say 2MB) than the segment file size.
> Also, the default preallocated size is only 16KB, which is also too small.
> We should change it to something like 4MB.
