I've noticed that scanning is somewhat of a slow process, but I've never
experienced that amount of slowness - there could be a problem with the
driver, so go to the manufacturer's website and make sure you're using the
latest one available. If that doesn't work, try switching the scanner to a
different USB port (if you're using a USB scanner). If you're using other
devices, or link several through a hub, try redistributing items so that the
scanner is on it's own port.

My general understanding is that scanning speed is based on several factors,

-USB1/USB2/Parallel Port: the newer USB2 spec is much faster, and allows
much faster transfer of data over the pipe. I think USB2 is backward
compatible (will run USB1 devices). The transfer speed can also be affected
by other USB devices, too. If the device is running over the parallel port,
you can expect it to be significantly slower yet.
-Computer speed: Of course, this is more than just CPU power, but can be
affected by the amount of memory you have in the machine, the bus speed,
caching, and a whole host of other things (for example, is you video card
built into the motherboard? If so, there is probably system memory reserved
for video processing, and that can decrease your system memory and slow the

I couldn't find anything specific on scanning times, but PCWorld has a good
article on choosing a scanner, with a review of several scanners.,pgid,36,00.asp

My advice: do some more research, and then go get the best model you can
