    3 
    4 FsOpBench is a file system benchmark targeted at testing interactive performance of busy file systems.
    5 fsopbench has three primary functions:
    6 
    7  * Create a artificial file tree with a realistic distribution of file sizes for user home-directories as described in
    8    [http://www.cs.vu.nl/~ast/publications/osr-jan-2006.pdf UV 2005] to provide a reproducible test setup.
    9 
    10  * Tree traversal while measuring the time required for reading the directory, stating the file, reading the first
    11    byte of the file and finally the performance for reading the first 128k of the file.
    12 
    13 When FsOpBench is started for the first time, it will setup a 20 GB file tree for testing. Make sure that you have about
    14 twice as much free space for it to work comfortably. In normal operation, FsOpBench will run three tests.
    15 
    16  * one reader running
    17  * three readers running
    18  * three readers and three writers running
    19 
    20 The 20GB filesystem tree is structured so that each reader gets its own part of the tree and as such can work on the disk and  not from the cache.
    21 
    22 The writers use the same code as was used to generate the original filesystem tree.
    23 
    24 When the program terminates, the output of the writers will be removed.
    25 
    26 FsOpBench is written in Perl and should run on all UNIX like systems.
