will open or create each file on the command line, and start a series
|
|
of aio to it.
|
|
|
|
aio is done in a rotating loop. first file1 gets 8 requests, then
|
|
file2, then file3 etc. As each file finishes writing, it is switched
|
|
to reads
|
|
|
|
io buffers are aligned in case you want to do raw io
|
|
|
|
This test takes less than a minute. It ends up writing and reading less
|
|
than a few Megs. It is a sequential workload. This test stresses the aio
|
|
interface not the disk, or kernel.
