lat_fs - measure file system create/delete performance
lat_fs [ dir ]
lat_fs is a program that creates a number of small files in the current working directory and then removes the files. Both the creation and removal of the files is timed.
If dir is specified, lat_fs will change to that directory first and do the creates and deletes there. Otherwise the creates and deletes are done in $PWD.
The results are in terms of creates per second and deletes per second as a function of file size. The output is in 4 column form and is the size of the file, the number created, the creations per second, and the removals per second. Output format looks like: 0k 500 1304 2740 1k 500 904 1663 4k 500 861 1647 10k 500 674 1516
