I am interested in relating the position of a file on disk and the I/O R/W performance characteristics associated with this position.
I have been able to find two benchmarks, but they are both for Windows (see images below). I would be interested in finding similar benchmarks for Linux with a view to running them on my own machines.
I would also be interested in knowing how one can find out the position of a given file (CHS - Cylinder, Head, Sector) on disk. I found this thread (and links within) interesting, but didn't tell me what I want to know.
Images from Windows benchmarks.
stat(to find the inode) and then find that inode inside the groups dumped by
dumpe2fscan tell me. You couldn't run the commands on one of your files and give a quick outline of what the numbers mean?
staton a file but
dumpe2fsmust be run on a block device. First line in the man :)
