Abstract
A reader electro-optically reads symbols associated with products to obtain read data, and a controller decodes the read data to obtain symbol data indicative of the associated products. Reading performance is assessed by collecting time-to-decode metadata by determining each decode time period that is taken for each symbol data to be successfully decoded, by associating the collected time-to-decode metadata with the symbol data, by comparing the collected time-to-decode metadata with a predetermined long amount of decode time that is indicative of a slow reading performance, by storing each decode time period that at least equals said predetermined long amount of decode time, and by storing the symbol data associated with each stored decode time period.
