I gather that you took the vncviewer .deb package that I published, installed it for the scratchbox PC_ARM scratchbox configuration, and ran it there. As a general rule, I've found vncviewer to be much quicker when run in the emulated environment than on the device itself. I plan to improve this in future releases of the software. However, as evidenced by the feedback from people in this forum, even the relatively slow speed of vncviewer on the device itself is adequate.
