findByUrl was slow, for example, renaming 50.000 small files, it has to go through a list of 50.000 items 50.000 times, so renaming that number of files takes more than an hour, now it takes less time, but baloo re-scanning and the dirlister re-scanning the directory doesn't help to reduce the time.
Renaming 3.000 small local files is done in less than 10 seconds.
Moving 50.000 small files from sftp://127.0.0.1/borrar to /borrar1, the first step, fetching data from the dirlister took more than 1 minute, now is instantaneous.
