Which version of reportlab are you using? I contributed some significant
preformance improvements to the qrcode generation, but I'm not sure if
they've made it to a released version yet. If you have the improved
version, you will have a QrCode flowable in addition to the QrCodeWidget,
which is sligtly faster.
