Hmm seems to be a reiserFS problem, since every one reporting this is using 
reiserFS, also the older reports are talking about reiser.

Unfortunately my media drive is 300GB big, so I'm not willing to change my 
ext4 filesystem to reiserfs now :)
But I might use another partition tonight and convert it. My other test 
collection of 25.000 images should fit on there.

Maybe I can see the speed issues, too.
Note that reiserFS is fragmenting quite fast, much more then all the other 
linux filesystems. So even if I create a test partition today, I'm not sure if 
I will see performance issues, since the reiserFS partition will be quite 

Do you know a script that can simulate a lot of disk activity, so I can try to 
fragment the partition in a short time?
