[Pkg-samba-maint] Bug#538079: samba: Dead Slow READ performance - WRITE Performance OK

[Tobias Goeller]

Package: samba
Version: 2:3.2.5-4lenny6
Severity: grave
Justification: renders package unusable


Hi All,

I have updated the server recently and since then CIFS or SAMBA Performance
using various clients (Windows, OS X, Linux) is dead slow when reading.

The Network is a switched Network (Zyxel Switch), SCP Performance is about
30-40MBit/s over wireless lan and about nearly 500MBit/s over wired lan.

NFS works fine, too.

SAMBA READ Performance, however, is about 10-150KBit/s - which is
awfully slow and renders the system unusable for everything
concerning file sharing.

This wasn't the case with earlier versions of samba on debian 5.0.2.

In case this bug is a duplicate of another bug existing please close the
ticket right away...

Kind Regards
Tobias Goeller
