ft crawl bandwidth Server Configuration Option
Applies to: SQL Server (all supported versions)
Use the ft crawl bandwidth option to specify the size to which the pool of large memory buffers can grow. Large memory buffers are 4 megabytes (MB) in size. The max parameter value specifies the maximum number of buffers that the full-text memory manager should maintain in a large buffer pool. If the max value is zero, then there is no upper limit to the number of buffers that can be in a large buffer pool.
The min parameter specifies the minimum number of memory buffers that must be maintained in the pool of large memory buffers. Upon request from the Microsoft SQL Server memory manager, all extra buffer pools will be released but this minimum number of buffers will be maintained. If, however, the min value specified is zero, then all memory buffers are released.
Under certain circumstances, the number of buffers currently allocated is less than the value specified by the min parameter.
This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
