Hi!
Maybe you are interested in my recent backup time comparison. I simply
copied the partitions with "cp -ax /.../a/. /.../b/" where "/.../b/" is
a freshly created reiserfs. I hope the comparison is readable and makes
sense for someone.
I'm not really glad with the first values of the "living" root
filesystem, partition 1. Did I forget something (except for taking
data=journal values, sorry) ?
Best regards,
Manuel

O.k.
I made a new comparison with just the data-logging patch replaced by the
new -24, and now, only using fresh filesystems. I added the related
lines from tonight to show the improvement.
File size distribution statistics are available via email upon request
(131kB as .tar.gz).
Best wishes,
Manuel

These results suggest that data=ordered should indeed be the default.
Good job Chris!
