Please, sorry me. The script I was using to test the performance difference between indexed and non indexed ext3 directories is not good. I have discovered it making a reiserfs filesystem and running the script on it. The results are the same for non htree ext2 and reiserfs. I believe that the problem is the time needed for exec the commands that are run into the script main loop. I have just used the C program that Daniel Phillips used in ist benchmarks: http://old.lwn.net/2001/1213/a/directory-index.php3 and now I can see the great performance gain with the indexed directory (I have just tested only the reiserfs, but I'm sure that the results are very great in the ext3 htree too). I'll test the new patch you have send to me. > So rest assured, we *are* working on the htree indexed directory code. > I fully intend for this to get integrated into the 2.5 tree, even if > we don't have the NFS readdir fixes done at first. :-D Greetings. - --- Carles Xavier Munyoz Baldó carles@descom.es Descom Consulting Telf: +34 965861024 Fax: +34 965861024 http://www.descom.es/ - --- -----BEGIN PGP SIGNATURE----- Version: PGP 6.5.8 iQA/AwUBPXi/hDvYAf7VZNaaEQLaigCgovJ+60UKp9fsCJmr5TcVjO0ctpQAn2q/ +mzwnOyaAx9zE1KlboRPsTPu =uTYn -----END PGP SIGNATURE----- _______________________________________________ Ext3-users@redhat.com https://listman.redhat.com/mailman/listinfo/ext3-users
