Sorry for my late answer.
I found the problem.
I was uploading and extracting the image in a Truecrypt container.
For some strange reason I expected that encryption/decryption wouldn't influence uploading and extracting the image.
I was wrong.
For very large files, Truecrypt reserves 75% - 100% CPU.
For now I only used Truecrypt on rather small files.
After a long search I carefully looked at 'top' and saw that truecrypt caused the slow extraction.

Tim,
Here is a little information about my setup which I use for storing
images for our
company. I have my desktop machine (FreeBSD 6.1) which is the G4U image
server also. I have two volumes. One is a storage area for images, the
other is a
work area. Due to the number of images I must keep all are compressed to
save
space and like you I need to be able to get access to the images fairly
rapidly.
To achieve this each of the volumes above is as striped pair of drives,
one USB
and one SATA. When I need to get access an image I deflate onto the work
drive,
ala:
cat /vol/image-file.gz | gunzip - > /vol1/image-file
I get about 70MB/s which is much much quicker than if both source and
destination
are on the same volume. Then I use a tool in FreeBSD to turn a file into
a block device
which I can mount. I'm sure Linux has something similar.
The image files can then be exported with Samba which is good for doing PC
migrations.
HTH,
Dominic
