I finally managed to finalize the upload of all the songs, and everything is working fine .
Some issues and remarks I encountered:
- I have 37.000 fids, everything is working fine
- the average upload speed via ethernet is only 0.45 MBps (including databse rebuilds etc.), a bit slower than I expected for an ethernet connection. It took me over 4 days to transfer all the songs
- running set_empeg_max_fid.sh is easy and quick, resulting in my case in the standard 44.000 (or so) fid-limit number
- running fidsift is best done via the serial port, not via ftp since it takes a very long time (couple of hours) to run it if you add 40 GB of songs
- fidsift gives a huge decrease in the database rebuild times. A decrease of 90% can be expected when you add 40 GB of songs
- Emplode is not very stable when you add 40 GB of songs. I encountered regular crashes on the transfer, resulting in very long (3 hours and more) database rebuilds and disk checks. JEmplode is more stable.
