+Samba-3.0.12 and later implements a solution for sites that have experienced performance degradation due to the

 The key was fixing the directory handling to read only the current list requested instead of the old
 (up to samba-3.0.11) behavior of reading the entire directory into memory before doling out names.
 Normally this would have broken OS/2 applications, which have very strange delete semantics, but by

 Of course, use your own path and settings, but set the case options to match the case of all the files in your

 The secret to this is really in the <smbconfoption name="case sensitive">True</smbconfoption>
 line. This tells smbd never to scan for case-insensitive versions of names. So if an application asks for a file
 called <filename>FOO</filename>, and it cannot be found by a simple stat call, then smbd will return file not
 found immediately without scanning the containing directory for a version of a different case. The other
-<filename>xxx case xxx</filename> lines make this work by forcing a consistent case on all files created by smbd.
