ft crawl bandwidth Option
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.
Note
Under certain circumstances, the number of buffers currently allocated is less than the value specified by the min parameter.
