While I have access to a loaner Sparc2, I've been trying to bench it against
my RS/6000 Model 320. I've been finding that the 6000 has about twice the
I/O throughput of the Sparc (1.5MB vs .75 MB ) using real simple read and
write system calls on large files (25MB). Other I/O related tasks
like multiple execl calls run about 2 times as fast on the 6000.

Both machines are using 3-4 MB/sec SCSI drives and both machines are running
with only a single user during the benchmarks. Both have 16 MB memory.

Is this consistent with what others are finding, or is there something 
wrong with this particular Sparc box?
