runzhiwang updated HDDS-3223:
-----------------------------
Description:
By s3gateway, write a 187MB file cost 5 seconds, but read it cost 17 seconds. I
use tcpdump to capture the packet of read request, just as the image shows. The
first 10 GET requests arrive from 3.54 second to 3.56 second. But the next 14
GET requests arrive from 4.41 second to 12.23 second.

By s3gateway, write a 187MB file cost 5 seconds, but read it cost 17 seconds. I
use tcpdump to capture the packet of read request, and find the last packet is
10 seconds later than the first packet. I think there are some problem with
aws-cli.
