I was attempting to measure random page cost a while ago -
I used three programs in this archive :
http://techdocs.postgresql.org/markir/download/benchtool/
It writes a single big file and seems to give more realistic
measurements ( like 6 for a Solaris scsi system and 10 for a Linux ide
one...)
Have a look and see if you can cannibalize it for your program
Cheers
Mark
