In smb.conf there is still a pointer to out-dated Speed.txt: samba-docs/smbdotconf/locking/oplocks.xml For more information see the file <filename moreinfo="none">Speed.txt</filename> in the Samba <filename moreinfo="none">docs/</filename> directory. </para>
Looks like this got fixed some time prior to 3.0.25.
Speed.txt is revived at Samba 3.2.4 :-(
Fixed with commit 52aa522a in master. Patch will be included in Samba 3.4.4. Closing out bug report. Thanks for reporting!
