was: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, read request read 10 parts in
parallel and then read the left 14 parts in sequential. So read cost 2 times
more than write.
