No. A bigger filesystem cache would only help if you had a lot of IO ( => high 
system or wait io value in vmstat). The problem seems to be the "application 
cache" of the thumbnails.

Did you check if you actually have files in .thumbnails?

I think you could have one of the following problems:

1. Thumbnail cache too small (don't know how to increase it further)
2. The thumbnails can not be written to the .thumbnail directory so the are 
generated each time (permission problem)
3. Whenever it is checked if your image has been changed since the thumbnail 
was generated the result is that the image is newer. So the thumbnail has to 
be regenerated. I don't know what the criterias are (timestamp or something 
else). Did you check the creation time of your original images (ls -l). Maybe 
they are in the future.

Q:	How did you get into artificial intelligence?
A:	Seemed logical -- I didn't have any real intelligence.
