As before, I'd appreciate some other results from modern systems to
compare with.
Alex, below you can find our LMBENCH 3.0-a4 test results.
Our machine is a Toshiba TX4937 based system (in the hope "modern enough") running with
333MHz CPU-Clock and 133 MHz SDRAM-Clock (64bit).
The bench was run on the Debian based mipsel-distribution.
I'm surprised about the big difference in test results compared to your RM9000 system.
I would expect that your system should be much faster and I think there must be
a blocking part (hardware, software) in your system.
Regards
Ralf (Roesch)
