-HOW TO TEST<br>
-------------<br>
-<br>
-1: Type "make"<br>
-<br>
- # cd<br>
- # tar zxvf fs-bench.tar.gz<br>
- # cd fs-bench<br>
- # make<br>
-<br>
-2: Change directory to terget file system and do-it!<br>
- (I always use one-HDD/one-partition for fs stress test.)<br>
-<br>
- # mount -t jfs /dev/hdc1 /jfs<br>
- # cd /jfs<br>
- # ~/fs-bench/test.sh 2>&1 | tee ~/fs-bench/jfs-test<br>
-<br>
-<br>
-NOTE<br>
------<br>
-<br>
-The size of files that are created for stress test is not fixed. The<br>
-file size are determined by probabilistic algorithm, box-muler<br>
-algorithm.<br>
-<br>
-number<br>
-of files<br>
