Hi everybody,

I'm suffering the same problem, sync and fsync are horribly slow. I've writ=
ten=20
a small test program:

http://www.earthworm.de/tmp/reiser4-fsync.c

with 2.6.13:
sync()                                  =3D 0 <0.000198>
fsync(3)                                =3D 0 <0.003353>

with 2.6.14 (with and without patch):
sync()                                  =3D 0 <2.092873>
fsync(3)                                =3D 0 <0.132579>
=2D-=20
