Really slow CO5

fabrizio cicconi
Hallo,

In the last time the CO-5.2 is really slow, I verify the mac permission and control all the external HD.
The problem is that above all when CO develop the raw file, Is difficoult work with photoshop and other program too. it become all really slow. I can not use 2 Mac for work, is for this that I hope that with CO in the future it will be possible make some other thing, like correct the architectural pictures and print.

I've another question, Is it possible like photoshop, when a make a change to see the preview?

Thak you best regards

    Solving performance issues is often a trial-and-error process. My first suggestion is to work without the external hard disk. Did a previous release of CO 5.x work faster? Can you give more details about your setup? What is slow about CO5? Do you have large number of files in a folder? Are you working in one session all the time?

    I make a session any work, I must work with external HD otherwise my mac be full in less time.
    Is only in yhe last time that CO5 is slow, Have I empty the cache or to do other things?

    I understand that you need your external HD. I suggested to remove it only for testing purposes, that is to see whether this affects the performance. As I explained solving performance issues is a trial-and-error process. If you are not in the position to try any suggestion, it can be very difficult to help solving.

    I came with a few questions in my previous post but you did not answer most of them.

    Ok then...
    The previous release of CO 5.x work the same
    Now with the same session in HD and in PC, work fast when only CO5 is open and develop few file, is really fast.
    When develop a lot of file is slower, but, above all when photoshop and bridge are open all the programs are slow. I've 4GB sdram, and I work with photoshop while CO continue to develop.
    I'm obligate to use all the programs, becouse sometime I've to get the pictures soon as possible to the client.

    My setup? I try: normally I develop tif 8 bit, I've P25 with contax 645, Clarity 30% mask contrast 200/350 it depend of the work. ask me other setup if you need

    In CO5 Is slow the focus tool and the image render preview, sometime when I work with another program whlie CO5 develop first to pass to CO i wait a lot.

    I hope to get you all the answer to the questions.

    Thank you

    I'm just curious Fabrizo, What computer do you have?,you said you have 4 Gig or ram but what cpu & speed, Mac OS, available hard rive space on boot drive and when shooting to external how much space is on it?

    Fabrizio, based on your extended information (thank you) I am almost certain that you run out of RAM memory when you develop images with CO5 while Bridge and Photoshop are running the same time. For me it is easy to bring a 4 GB RAM system on its knees in such a setup.

    You can check yourself very easy with Activity Monitor (Programs, Utilities). For an easy readout, start the program and right-click on the Dock icon, go to Dock Icon: Show Memory Usage. As long as you see the Dock, you can dynamically monitor RAM use. Green is fine, Red and Yellow is in use, Blue too but inactive. When your icon does not have much Green left, your system will become sluggish.

    In similar setups (CO5, Photoshop, 4 GB RAM) I advise users not to open both programs simultaneously but sequentially. And because closing CO5 does not regain all used memory unfortunately, a restart after CO5 processing and before Photoshop post-processing is strongly advised. Again, Activity Monitor can give you real-time visible guidance.

    The reason that a system slow down when all RAM is occupied, is that the disk will be used for (swapping) memory pages which does not fit into RAM anymore. At the same time CO5 is storing developed images, writing files to disk and Photoshop uses the disk as swap disk for all edits. That's becomes a long queue in no time. A second disk, like your external disk, gives some relief when CO5 and/or Photoshop can write to it while OS X is swapping pages to the internal disk. But it is slow anyway.
