--- Comment #14 from Poornima G <pgurusid at redhat.com> ---
Apologies for the delay, there have been some changes done to quick-read
feature, which deals with reading the content of a file in lookup fop, if the
file is smaller than 64KB. I m suspecting that with 5.3 the increase in
bandwidth may be due to more number of reads of small file(generated by
quick-read).

Please try the following:
gluster vol set <volname> quick-read off
gluster vol set <volname> read-ahead off
gluster vol set <volname> io-cache off


And let us know if the network bandwidth consumption decreases, meanwhile i
will try to reproduce the same locally.
