A data decoding system that includes a server-side proxy component and at least two back-end computers, where the server-side proxy component is configured, when it receives a decoding request from a client, to select a back-end computer to forward the decoding request to, based on either a pre-defined rule, load estimates for the at least two computers, estimated network throughputs across network paths to the two computers. In response to receiving this request, the back-end computer that is selected is configured to decode the request, which is an image of decodable indicia, by locating the decodable indicia within the image and decoding it into a decoded message. The decodable indicia was provided by a raw image byte stream, a compressed image byte stream, or a partial compressed image byte stream.
