<para>

This boolean option tells <command moreinfo="none">smbd</command> whether to
|
|
issue oplocks (opportunistic locks) to file open requests on this
|
|
share. The oplock code can dramatically (approx. 30% or more) improve
|
|
the speed of access to files on Samba servers. It allows the clients
|
|
to aggressively cache files locally and you may want to disable this
|
|
option for unreliable network environments (it is turned on by
|
|
default in Windows NT Servers). For more information see the file
|
|
<filename moreinfo="none">Speed.txt</filename> in the Samba
|
|
<filename moreinfo="none">docs/</filename> directory.

Oplocks may be selectively turned off on certain files with a share. See
|
|
the <smbconfoption name="veto oplock files"/> parameter. On some systems
|
|
oplocks are recognized by the underlying operating system. This
|
|
allows data synchronization between all access to oplocked files,
|
|
whether it be via Samba or NFS or a local UNIX process. See the
|
|
<smbconfoption name="kernel oplocks"/> parameter for details.
