I also checked tabulated, numeric value for the same... under Ports menu.

This difference how calculate 'Last' rates in db and rrd:
 - DB calculate real rates betwen 2 poll times
 - in RRD graphs 'Last/Now' rates calculate betwen (current time) and (current time - 300),
  but betwen current time and last poll time RRD artificially fills with zero data..

Therefore rate in the graph is lower than from DB..
