This is your first problem, on my server (just a workstation), it takes less
than 10s to add 200,000 records...

The accurate query on jobid=10,13 will work on 2,000,000 + 200,000 files
(this is
the argument), as each filenames are different, you can expect to retrieve
2,2M files.
It's quite possible that it miss a *10 mutiplication somewhere in debug
