It depends on parallel port hardware speed, flash memory organization 
and boundary scan register (BSR) length.

My today's experience:
- JTAG adapter: simple parallel port dongle
- Oxford Semiconductor Ltd VScom 011H-EP1 1 port parallel adaptor
   (fastest than my standard parallel port on MB)
- a part with BSR length > 500
- flash memory (intel strataflash) 1 x 8 bit width
- flashing speed (it includes verifying):
   about 22 minutes per block (128 KiB)

For 32 bit flash organization the speed should be about 6 mins per 128 
KiB.


Have a nice day.
