Hi,

Does anyone perform Dhrystone 2.1 benchmark with a 405GP  ?
I've tried and i got : 172 Mips  (Walnut board @200Mhz, HHL2.0).
I've also tried to run the same benchmark with the same board with the
basic_os and the ibm "highcppc" compiler and i found
237 Mips (the 405GP specifications give 282 Mips @200Mhz, they told me that
was obtained with a Diab compiler).
Is there any reason my result (172 Mips) is so far from ~240 Mips.
(i've used  : ppc_405-gcc   -DUNIX -DROPT -O2 -fomit-frame-pointer   dhry21a.c
dhry21b.c timers_b.c -o dhry21 )

thanks,
Phil.
