[gthumb-list] Extremely slow loading of thumbnails

[Greg Mansfield <G Mansfield computer org>]

I'm using gThumb 2.90.1 built today from the git repository on Fedora 16.

I started gThumb at a directory of 600 JPG images about 6Mb each (total size 3.3Gb). 
After 2-1/4 hour of constant disk activity and over 70% CPU, it was still going strong and 
had consumed about 1.5Gb of ram and was growing. Only about 1/2 of the thumbnails were 
displayed.  I gave up and shut it down.

My machine has a 3GHz Phenom II X4, 8Gb RAM, 74GB Raptor system drive, 640Gb data drive 
and a 2Gb SSD.  The thumbnails for all 600 images are cached in the SSD.

gqview the predecessor of gThumb displayed all the thumbnails in less than 10 seconds.

I put together a 320 line test program using GTK+ functions to read and display 
thumbnails. It took about 5 seconds to display all 600 thumbnails.

It seems to me that there is something seriously amiss.
