The untuned Avision backend (again a copy of the Tamarack one when I
started to adapt it for Avision scanners in 1998 or so) was never (!!)
that slow! You might simply throw your scsi adapter into a
garbage-can!

I have an Adaptec Ultra-SCSI controler (AIC-7861) and a (lowend) NCR
Ultra-SCSI one. Giving me both the same good performance even when
plugged into a Pentium-I 120Mhz ...

The unmodifed Tamarack code had the same speed as the windows driver -
and some reported a speed improvement of the factor 5 (!!) when
scanning under Linux (ok - this might have been a Win~1 problem - not
a Linux feature ;-)). My tuning yield some 5 - 10% of extra
performance. (ok - my scanner is still much slower than the new Epson
USB onces :-((()
