-c
Set the cache size for hash and btree makemap command-line switch

The -c switch instructs makemap to set the cache size for hash or btree databases to the number of bytes indicated: 

% makemap -c 524288 hash  outfile

The default cache size, if this switch is not specified, is 1,048,576 bytes (1k squared). Note that setting the cache size is an art, and that the larger the cache, the better. The minimum cache size is recommended to be no less than 10 pages, or about 40,960 bytes.
