CFFILE reads the entire file into memory before acting on it. Even appending to
the file requires it be read into memory first. That's where your memory usage
is likely coming from -- though not sure why it's not being freed in a timely
manner.

If you are storing .2 to 5mb of data per user for an unknown period of time,
yes you are using a lot of memory.
You have entered the relm of serious design where trade offs between file reads
versus memory versus cpu time have to be weighed and

into Robi's blog post.

Where is this data being stored? Is there code to clear the data? I.E. If the
