Trying to import a QIF file with 2000 investment transactions (converted from CSV to QIF using CSV2QIF) under new account in Quicken 2011 Home and business, the file imported within a minute. I decided to import it the second time to emulate the import under existing account. This time the same file took 20 minutes to import – much longer than the first time.

Keep this mind when you have thousand transactions file to import for an investment account. It might be good idea to break the file in chunks and convert and import them separately – this way you know already imported parts are done.
