I tried to export a table to csv. The table had 400000 records. The Parse Count and status were updated only 50000 records.
It gives the user the impression the script is not working (until seeing 5000 records done) or that the script has stopped working since it takes about 3 minutes to export 50000 records.
The time should be updated each second at least if not millisecond. It is currently updated only after each 50000 records.
