Unexplainable disk activity after simple select statement

I am trying to export database tables to ascii files for archiving. I basically write straight sql code that will spool the output of a select * from table statement. For each entry, I have to do this 62 times. That is, I have to open, write the output of the select statement, and close the file 62 times for each entry that I process.

The strange thing, the select statement seems to work fairly quickly but then afterwards I have a lot of unexplainable disk activity that is slowing my outputs to a crawl. The larger the output that is generated from the select statement, the longer the stall seems to be.

Any ide what is going on?

Any help would be greatly appreciated.
