-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, just one more idea that came to my mind,
reiserfs uses a technique to save small files in the filesystem tree which uses less disk space then. In ext3 a 1 byte file will take up 4k, while this is not the case in reiserfs. This yields a performace hit of about 5% (people say, not that i have measured anything) If you have enough free space you can disable this, make the small files consume more space again and gains some speed improvement. Another thing you could do is disable the writing of accesstimes. Read man mount how to do this. The mount options are noatime,notail. Concerning your observation I would start looking at how the fragmentation is measured. Maybe this also depends on the filesystem implementation in the kernel. Anyway: you can not get much better 1.043.. parts per file. This means that almost every file(96,12 % in your case) is contiguous. have fun |> | | I did a little test. Something fishy here.
