Performance question

I have a db which contains also response documents. Response documents are represented only in one column (Show only responses is selected). This column has very complicated formula. My question is: is it better to have this column as it is OR to create computed field in the response documents and there to put this formula?

Thanks in advance.

When you have a complex formula it is always better to have it as a computed field rather than having it in the column formula. This increases the performance.
