Ah, just as I was done sending the other mail, I noticed something: There are 
some file accesses to some path under "/mnt/server/...". Are your files lying 
on an nfs share, by any chance?

I imagine that the thumbnail creation (hitting on a lot of files) may not play 
along well with a high-latency storage. AFAIK the ImageManager cancels 
thumbnail requests for low-priority thumbnails when others are more urgent. If 
you add a high-latency storage into the mix and start scrolling/browsing your 
images, most thumbnail requests are probably cancelled before they start.


Maybe the long time spent in futexes could also mean that KPA gets preempted a 
lot because of NFS being too slow (for KPA's heavy access patterns). Is it 
only KPA that becomes slow, or does it tear down the performance of other 
desktop programs or the file manager?
