I doubt this has any relevance whatsoever, but when I try this on a
2.2.16
kernel running on top of a Pentium Pro 200 w/96megs of mem w/ a SCSI 2
disk, I get some funny numbers:
matt@zeus:~/cwork/personal$ ./elv_test 8 30
files created, 240 megs written at 4.32 megs/sec
finished writing 240 megs written at 1794.23 megs per sec
finished reading, 240 megs read at 1675.813817 megs/sec
Any ideas why I would be getting these numbers?

That will teach me to play fast and loose with checking error returns
from system calls. I wasnt specifying a mode when creating the files.
So they were being created without user write permission..
I dont know why it worked under 2.4.0. Maybe a kernel bug :-).
Anyway, a new version is available now at
