I ran unixbench-4.1.0-971022 on an SS20 with 2xRoss 626 Hypersparc 150MHz
256M RAM, and 2 internal 2G drives; and a P6x2 233MHz 450GX Adaptec 294X UW
with interleaved FPM.

Sparc is gcc version egcs-2.91.60 19981201 (egcs-1.1.1 release)
P6 is gcc version egcs-2.91.57 19980901 (egcs-1.1 release)

You can find the benchmark at:
ftp://ftp.tux.org/pub/tux/bench/System/unixbench/unixbench-pre4.1.0-19971022.tgz

I see big improvements between 2.0.35 and 2.2.1 in system call overhead,
exec throughput, context switching, process creation. 
A drop in pipe throughput on Sparc?!

SMP is tested with 8 concurrent shell processes; 2.2 improves here also.

Disk is SCSI II narrow on Sparc, UltraWide on P6.

System Call Overhead on 2.2.1 is better on Sparc!

2xP6	     2.2.1 Final: 78.8	2.0.35 Final: 53.3
