Benchmarks
This page tries to give you an overview over the available benchmarks of our Zorro II USB controllers
ALGOR / HIGHWAY and the clockport USB controller SUBWAY. All benchmarks were made
with normal production cards in our laboratory.
As the test computer equipment certainly has an influence on the benchmark results we also list the
computer configuration of the Amigas used for benchmarking.
There are no comparisions made between our products and those of our competitors.
We have to leave that to you.
The USB devices listed in the tables below are internally organized as SCSI devices. Poseidon therefore has
to convert all SCSI commands (and all data packets) into small USB packets (of 64 bytes maximum size).
Moreover, there is an overhead originating from the USB protocol itself (SOF, handshake, ...)
DENEB
All benchmarks were made with Chris Hodges USB stack Poseidon (version 4.00).
Transfer rates were measured using SCSIspeed V4.2, MaxTransfer in Poseidon was set to 2MB and
a 256kB buffer was used in SCSIspeed.

The Fast Zorro II operation of DENEB on the ZIV busboard is dependent on the CPU card used. Some models may
not allow stable Fast Zorro II operation; in this case normal Zorro II mode must be used.
Due to the number of available CPU cards with all different timings we cannot guarantee Fast Zorro II operation.
ALGOR / HIGHWAY
Benchmarks were made twice. Once all CPU caches were switched on (1), once they were switched
off completely (2). This shows the influence of CPU power on measured transfer rates.
The test computer equipment is listed below each table.
All benchmarks were made with Chris Hodges USB stack Poseidon (version 2.00).
Transfer rates were measured with SysInfo (several tests were made and an average value calculated;
these values were checked against results from Sysspeed V2.6).

SUBWAY
Benchmarks were made on a standard Amiga 1200 (desktop) with different turbocards.
For better comparisons a measurement was made with SUBWAY on a Zorro card clockport.
Unfortunately this card was not able to deliver the needed spinup current for the ZIP 250.
The transfer limited reached on the Amiga 1200 reflects the relatively slow clockport access.
On Zorro clockports, the SUBWAY reaches comparable transfer rates as the HIGHWAY.
