Cisco Data Meter vs GIST
The new Data Meter from Cisco is unreliable. The tried and true GIST , for which Support will end on October 31, 2014, shows results as much as 10Mb less than Data Meter. In my book there is no enhanced speed test provided by Cisco Data Meter (CDM), and the important bar graph provided by GIST is not available in CDM. While there are some new features (like monthly bandwidth usage and projection), the inconsistent speed detection of CDM makes the primary reason for using the tool almost moot.
