Hi,
I have applied the patch you indicated me to my kernel. Compiled it with
support for the ext3 htree indexed directory and boot the computer with the
new kernel.
I have build a very simple script to test the speed differences between a non
indexed ext3 directory and an indexed one. At the end of this email is the
script source code.
How you told to me, when I create a new directory it will be by default
indexed if superates the block size.
I have run the script to create 10000 files over a newly created directory
(indexed directory) and over an existing directory (no indexed directory).
Indexed directory results:
Fri Aug 23 13:27:23 CEST 2002
real 1m17.092s
user 0m23.260s
sys 0m52.250s
Fri Aug 23 13:28:40 CEST 2002
No indexed directory results
Fri Aug 23 13:29:24 CEST 2002
real 1m18.658s
user 0m23.370s
sys 0m48.200s
Fri Aug 23 13:30:43 CEST 2002
But this is not the expected result. The indexed directory must be more quick.
The output of the lsattr command over the newly created directory is:
- --------------- ./test
No flag indicating that this is an indexed directory.
I believe that I'm doing something bad.
How may I know if the kernel I have build really has htree support ?
What am I doing bad ?
