Dúvidas QVD

Pessoal, uma dúvida .

Tenho uma tabela que possui 54 milhoes de registro.

Quando gero um QVD dessa tabela ele gera um QVD de quase 2 GB.

Dúvida é, esses 2GB esta com tamanho normal para tamanho da tabela ?? é uma tabela com uns 10 a 12 campos !!

Atenciosamente,

The size of the qvd depends on the contents of fields: lenght of the field, number of distinct values of the field.

Sometimes it's possible to reduce the size splitting fields, ie a timestamp in date and time.
