| 7 | This boolean option tells <command moreinfo="none">smbd</command> whether to
|
|---|
| 8 | issue oplocks (opportunistic locks) to file open requests on this
|
|---|
| 9 | share. The oplock code can dramatically (approx. 30% or more) improve
|
|---|
| 10 | the speed of access to files on Samba servers. It allows the clients
|
|---|
| 11 | to aggressively cache files locally and you may want to disable this
|
|---|
| 12 | option for unreliable network environments (it is turned on by
|

| 13 | default in Windows NT Servers).

| 17 | Oplocks may be selectively turned off on certain files with a share. See
|

| 18 | the <smbconfoption name="veto oplock files"/> parameter. On some systems
|
|---|
| 19 | oplocks are recognized by the underlying operating system. This
|
|---|
| 20 | allows data synchronization between all access to oplocked files,
|
|---|
| 21 | whether it be via Samba or NFS or a local UNIX process. See the
|
|---|
| 22 | <smbconfoption name="kernel oplocks"/> parameter for details.
