Did some tests:
ct60 -> dsp hostport.w = 3.2mb/s
ct2b -> dsp hostport.w = 4.6mb/s
both machines have 50mhz DSP + accelerated mobo + fastram. ct60 machine, however, mobo is clocked at only 20mhz. Switching down to 16mhz made no difference. My turbo switch may be faulty.
the software that measured the xfer rate uses NO handshake on the Host side, and status polling on the DSP side.
The host port itself must be the limiting factor. With the ct2b able to access the host port faster than the ct60.

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
