rotateblit and xscale

The PXA250 had some "problems" with its cache. That may or may not be affecting you.

Are you sure your source is in the same type of memory (i.e. you're using a "general" memory buffer rather than a buffer GAPI passes you for the source of the rotation)?

Try to run the same test using system memory only ( blit from one part of memory to another - no framebufffer ) and see if it is any faster.
If it is then perhaps you are dealing with a device that is using MediaQ GPU chip ( Toshibas etc ) - accessing framebuffer memory is very slow on these devices.
