> By s3gateway, write a 187MB file cost 5 seconds, but read it cost 17 seconds.
> The write and read request both split the 187MB file into 24 parts, write
> request write all the 24 parts in parallel, the read request read 10 parts in
> parallel and then read the left 14 parts in sequential. So read cost 2 times
> more than write.
