How long should it take to convert a "raw" camera file to a
"default" JPG?

My machine is pretty old (Pentium 4, 2.40GHZ)

It takes a minute or two of CPU time to convert a Fujifilm FinePix
S100fs RAF file to JPG taking "default" conversion parameters.

I tried FinePix Viewer that came with the camera and
s7raw (arbitrarily selected from Google searches and located
at www.geocities.co.jp/SiliconValley-PaloAlto/9919/s7raw.html)

The camera can store directly as 3MB JPG files much
faster than it can store 23MB RAW files.

Can someone suggest parameters that are faster than the
defaults in FinePix Viewer or a faster converter and
defaults?

I don't mind spending some money (I have Adobe CS3 Premium
and am willing to upgrade to CS5) but I don't feel like
using all of the space that CS takes compared to even FinePix
Viewer.

Dcraw is wonderful for what it is, but its user
interface is not meant for general purpose conversions.
A photographer needs an interface that allows previewing
results in order to select appropriate options for best
results.

UFRAW is probably the best front end for dcraw. It
provides all of the necessary options for a general
purpose RAW converter. It can produce JPEG images
directly (as well as TIFF or PPM images). It can also
be configured to generate only an "ID" file, which
contains the configuration used by the interactive
adjustments so that they can be used by the batch
processor.

For example, I just ran off converstions on 65 RAW files
(14-bit compressed NEF files from a D3S) as a batch.
Since all of these had virtually the same
characteristics, only one image was actually done
interactively. Then ufraw-batch was invoked on the
entire list of files, using the ID file to set the
configuration:

ufraw-batch --conf=DSC_0001.ufraw *.nef

At other times, when each shot requires individual
configuration, I invoke ufraw interactively on the
entire list, and produce an ID file for each image.
Then ufraw-batch is invoked on the ID files:

ufraw-batch *.ufraw

In fact though, I cheat. I use Linux and have a script
that determines how many CPU's the system has and then
feeds a loop that keeps all of the CPU's busy. One box
that I use has 4 CPU's, and another has 8. The script
works them to the max. The 4 CPU box processes images
at 6 seconds per image. (If ufraw-batch is invoked
normally, and uses just 1 CPU serially, it takes 21
seconds per image on that particular system.)

depends on the size of the raw file, software and computer.

how much memory?

that camera is 11 megapixels and 1-2 minutes is absurdly slow. it
shouldn't be than about 10-15 seconds, and even that is long.

upgrading photoshop won't make raw conversions that much faster (but it
may be worth it for other reasons), however, a new computer with a lot
of memory will.

dcraw is one of the slowest raw converters.

That's not such a slow system. How much memory do you have? If it's less
than 2 gigs, that's probably the bottleneck. Memory is cheap.
