i would believe the interface throughput statistics before a third party, internet based speed tester.
it is clear from the interface output that you got no higher than 70kbps in the 5 minute window.
you can max out this interface statistic by pushing a very large file and viewing the output every 30 seconds or so until the file is completed. with a big enough file, and no other restrictions, you should be able to get TX throughput towards 128kbps. (unless its a download then the RX will increase)
