Usage transactions should NOT be used as an extraction tool to
perform the mass export of measurement data.
Saving derived interval data and sending the data to an external
system via the "Save Interval Vector" and "Extract Interval Data"
options on the "Vector and Service Quantity Math" and "Get Interval
Data" usage calculation rules can have a noticeable impact on usage
transaction processing. Usage transaction processing can be improved
by up to 45% if extraction of interval data is eliminated. Use of
these options should be limited to situations in which they are absolutely
required.
Use the Usage High Low rule instead of the VEE High Low rule where
possible.
For Outbound Messages, the schema extraction for usage transactions
should be converted into a RAW string operation to allow for more
efficient Pre-Processing logic.
