It can also be controlled by setting the following registry keys (also included in the attached .reg file:
So over time, the word suggestion database grows larger and larger due to the fact that the leftmost characters of the barcodes are all the same and the delay between each character increases as the system searches the database for a match.
See the attached video which demonstrates the data entry lag.
