No, stock userland relying on the ld.elf_so preload trick for v8 CPUs.
So theres a little bit to gain for this timing. Note, however, that
the sparc64 machine nearly is a linear improvement on this value, so 
I don't expect much.

Compiled for v7 CPUs it should be *much* slower.
This machine needs 246 seconds:

mainbus0 (root): SUNW,Sun 4/75
cpu0 at mainbus0: cache chip bug; trap page uncached: CY7C601 @ 40 MHz, TMS390C602A FPU
cpu0: 64K byte write-through, 32 bytes/line, hw flush: cache enabled
