help with the GIMP
 

Hi

I am trying to make the transition to the GIMP from Photoshop 7 (Mandrake
9.2). I use PS for editing high res scans (50-70MB). When using the GIMP I
have been experiencing some extremely long processing times when doing
routine tasks such as colour balancing and unsharp masking. When colour
balancing I can watch the image redraw itself from top to bottom, and USM
can take up to 30 seconds or so.

I have a relatively new system (AMD 2600+, 512MBddr400, 80GB-8MB cache HD,
etc.) and these tasks complete themselves instantaneously (for all intents
and purposes!) under WinXP + PS7.

I am very new to Linux so I don't know where to start, although I have
increased the GIMPs cache up to 256MB in the preferences.

Any ideas?

Thanks

How long history do you use? 70MB image + one 70MB previous version +
70MB work buffer + some variables = 256MB. In other words, if the image
processing SW (whatever brand) stores more than the previous version of
the image, it will run out of cache, and starts swapping to the disk.

You might get some more help in comp.graphics.apps.gimp if your provider's
usnet server has it.

What "services" do you have running? Open the mandrake control center and
kill anything you don't need/aren't using like portmap, nfs etc. Like
windows, anything you have running in the background uses up resources.
Most of these distros load up the kitchen sink by default and people
install all sorts of things like web servers etc without realizing it. KDE
"system guard" will show you what is running etc.

Another thing that will help when using processor intense applications is
to use a "lighter" window manager like WindowMaker, icewm or blackbox etc.
KDE and Gnome have all sorts of background processes running to "integrate"
the desktop which you don't need when using something like The Gimp. If
WindowMaker is installed (if not, just install as it comes with the
distro..), type ctrl,alt,backspace which will dump you into a console/dos
like window, then type startx WindowMaker (case sensitive) and you'll get a
different desktop which uses very little resources. To get back to your
normal desktop, get back to the console and type startx.

Even booting into a graphical login takes up resources and there is no good
reason to do that either. Just have it boot to a console, log in and type
"startx".

Lots of options on how to configure the machine, I think they assume most
people want a cutesy desktop and integrated apps as most never use anything
very processor/memory intensive like the gimp with large images. I have a
feeling it's more how the whole system is set up and the desktop you are
using rather than settings in Gimp.
