Building Histograms

When I have several images open in PSCS, and edit one, then save and close it the system goes into a protracted period of "Building Histograms" with a progress bar. It appears to repeat this for every image thats open (and possibly one extra time)… Needless to say this is VERY slow and is one of the performance hits that have made this product rather disappointing.
HOW do I turn this crap off?

No problem here like that!

OK, this POS product is still doing the same thing, so let me try and ask the question better…….

Someone, on a Windows machine with PSCS… Go into PS, pull down Window and turn on the Status bar.

Now open a half dozen reasonable sized .psd files – mine are typically 70MB before doing any work…..

So now you’ve got a half dozen files open. Take one and modify it. Then do a Save As. Then CLOSE the file…….

NOW, do you get a VERY long, slow wait while the status bar says "Building Histograms" and SLOWLY shows progress, repeating at least once for every file that’s open?

If yes, how do I turn this crap off? If NOT, why does it persist on doing it on my machine, and again, HOW DO I TURN THIS CRAP OFF?

Too much coffee or are you always like that.
By the sound of it there is a POS somewhere but I bet it is your machine. Care to tell us about its specs (cpu, ram)?

3.4 GHz with 2GB of DDR400 memory, 1.1TB (yes, terabyte) of disk in Seagate
Barracuda drives all turning at 7200 rpm. ATI 9800 video….. AVG AND McAfee BOTH say there are no viruses. Ad-Aware and Spysweeper say there’s NO spyware or adware… ALL disks are defragmented weekly.

The SAME machine also gets used for real work and runs Embarcadero perfectly, Oracle PERFECTLY, Oracle Developer with NO performance problems, and SQL Server also with NO performance problems……

Needless to say, with the current incarnation of PS all the above are shut off before running Photoshop. With Photoshop, the performance issues go beyond the one I stated, but its a good example of what I’m seeing.

Now that you’ve got info on the box do you have anything useful to contribute? As in WHY its generating histograms every time I close an image and HOW TO TURN THIS CRAP OFF? And no, I don’t drink coffee, and YES I’m always like this with software that’s in its 8th major incarnation and still runs as poorly as this does.

I’ve never seen this myself, but I would look at the "Memory & Image Cache" settings. There is an option "Use Cache for Histogram Levels". Is that checked? If so, uncheck this option and see if that helps. The number of cache levels could also be too high. Set this to 8 if it’s now much higher.
