[Ocfs2-devel] results of inode performance

[Ling, Xiaofeng]

I have some test for the inode operation, below is the results. 
1-mkdir 2-rmdir 3-rename 4-mknod for regular file 5-unlink for regular
file.
--------------------------------------------------------------------
Just after mount:
[root at ocfs1 src] ./bend -1
total:100, rate:664.5 dir/sec
[root at ocfs1 src]# ./bend -2
total:100, rate:11217.0 dir/sec
[root at ocfs1 src]# ./bend -1
total:100, rate:2442.3 dir/sec
[root at ocfs1 src]# ./bend -3
total:100, rate:1487.2 dir/sec
[root at ocfs1 src]# ./bend -4
total:100, rate:2452.6 dir/sec
[root at ocfs1 src]# ./bend -5
total:100, rate:18066.8 dir/sec
-------------------------------------------------------------------
another try after a while

[root at ocfs1 src]./bend -1
total:100, rate:2404.3 dir/sec
[root at ocfs1 src]# ./bend -2
total:100, rate:16186.5 dir/sec
[root at ocfs1 src]# ./bend -1
total:100, rate:2391.4 dir/sec
[root at ocfs1 src]# ./bend -3
total:100, rate:1992.4 dir/sec
[root at ocfs1 src]# ./bend -4
total:100, rate:2402.5 dir/sec
[root at ocfs1 src]# ./bend -5
total:100, rate:13383.3 dir/sec

=====================
another try for 1000 subdir or file
[root at ocfs1 src]# ./bend -1 -p 1000
total:1000, rate:1161.0 dir/sec
[root at ocfs1 src]# ./bend -2 -p 1000
total:1000, rate:4869.9 dir/sec
[root at ocfs1 src]# ./bend -1 -p 1000
total:1000, rate:1124.3 dir/sec
[root at ocfs1 src]# ./bend -3 -p 1000
total:1000, rate:1096.3 dir/sec
[root at ocfs1 src]# ./bend -4 -p 1000
total:1000, rate:452.1 dir/sec
[root at ocfs1 src]# ./bend -5 -p 1000
total:1000, rate:7009.4 dir/sec
