| Data type | Range | Default value |
|---|---|---|
| REG_DWORD | 0 | 1 | 1 |
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 reads the data immediately thereafter, or writes data and then unlocks it immediately.
| 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. |
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.
