I tried to export a table that had 401510 records. Each line has at most 500 characters. It took 25 min and 42 seconds to do so. The resulting file is 87 MB.
The time is huge especially since it takes less than 3 minutes to perform an unloaddb and this is just one of many tables.
Another issue is the fact that Data Count does not match Parse Count. I know this is due to the fact that entries have been entered in the table since the export has started, but it looks like an error when the values do not match.
