60MHz R4400 (DECsystem 5900/60), src via NFS:
143.4u 29.7s 3:05.16 93.5% 0+0k 313+1178io 391pf+0w
With the DECsystem, 60MHz is the external clock speed, not the internal
doubled clock speed - eg, lmbench reports 119MHz. I'd say you should
be getting about the same performance as my DEC box all things being
equal. I'm guessing that the C compiler doesn't do FP - that'd kill
the VR4121...
