well, I used the IFS driver to copy my stuff onto the disk right now, it works really fast and nice.
install doesnt even require a reboot 😉
edit:
omfg, i just let mt-daapd do an initial scan of my whol collection, without those ‘huge’ ogg files. they no longer cause a SIGHUP or OOM, but still take ages i guess. anyway.
it scanned 7602 songs in 396 seconds.
on the NTFS, it took like 6000 seconds for the same action. go figure. (!)
