Im a generating a 25x25 QRCode using ZXINGNET class library. On my Fez Spider + T35 setup it takes about 12 seconds to generate the QR, converting it to a bitmap and finally see it on the T35.
Im sure there are ways to speed things up a bit? Generating one in a backend service might be a solution if nothing else is available but would like to see if i can do it more efficiently locally first.
Any ideas are welcome
