I think the most likely explanation is that the examples have all been changed so that they render into a linear RGB buffer, which is converted to an intermediate sRGB buffer before being sent to the screen. The conversion to sRGB could potentially be quite time-consuming on a low-performance device.

Did you mention in one of your mails that the blenders had to be changed from using integer math to floating point math? Or is all the code exactly as before your changes when changing that define to AGG_SBGR24?
