   My Gigabyte motherboard with dual pentium 166MHz MMX and an onboard
7880
does much better than this.

The figures below are rough estimates as I don't have the computer here
at work.

The original 2.0.30 kernel, did about 8MB/s, I had to specify
aic7xxx=ultra, to get 20.0MB/s
bus speed. Tagged queueing was disabled.

The latest 2.0.32 kernel, with tagged queuing enabled, does 'only'
6.7MB/s, still considerably
more than the figures you quoted.
