as your are appending to an open file, I would have thought that is the best way, other than doing it all in memory. Here are a few things to try. How about using a database and then exporting the data to a CSV file when you need it. Or how about setting up a CSV file as a datasource and writing to that. And finally, there are some CFX tags around for writing to CSV files, you could give one of them a try.
