Strange performance issues on Debian/Lenny compared to Ubuntu

[Olivier.LeCam at crdp.ac-versailles.fr (Olivier Le Cam)]

Ooops, I have cc the wrong command on the Ubuntu server. Please correct:

 > ubuntu:# dd if=/gl_nunki/file_test of=/dev/null
 > 524288+0 records in
 > 524288+0 records out
 > 268435456 bytes (268 MB) copied, 3,15924 s, 85,0 MB/s

with:

# dd if=/dev/zero of=/mnt/file_test count=262144 bs=1024
262144+0 records in
262144+0 records out
268435456 bytes (268 MB) copied, 5,56942 s, 48,2 MB/s

Sorry for that!
