Determines whether the lock-and-read and write-and-unlock performance enhancements are enabled. These features improve performance when an application locks data and then immediately reads the data, or writes data and then immediately unlocks it.

Value

Meaning

0

Lock-and-read and write-and-unlock features are not enabled.

1

Enables the lock-and-read and write-and-unlock features.

Note Image Note

Windows 2000 does not add this entry to the registry. You can add it by editing the registry or by using a program that edits it.

Caution Image Caution

Setting this value to 1 usually improves performance significantly. However, it degrades the performance of database applications that lock a range of data and do not allow data within that range to be read.
