db_file_storage_config_t::buffer_count The number of buffers in the database cache. The default value is DB_DEF_BUFFER_COUNT. To provide efficient access to database files, recently used pages are kept in a cache in memory. This option controls how much memory is used by the database cache. Each buffer is the size of a page, so the total size of the cache is page_size * buffer_count. See also: DB_MIN_BUFFER_COUNT, DB_MAX_BUFFER_COUNT, DB_DEF_BUFFER_COUNT
