Ram usage

=====
Hello all
So I recently upgraded my ram to 32gb so I could process more images but I was wondering if 170 images taking 2 hours to process dtm+dsm is normal? Also I tracked ram usage and never did the program use more than 2GB ram! Why did I upgrade to so much ram if it only uses 2GB or less? I set the process as high priority in task manager but that did not have any affect?

  1. Is this processing time kind of normal? If it is that’s ok just need to know
  2. Why is it not using more ram? I had nothing else running.
    Thanks for any help :slight_smile:

Welcome!

  1. We’ll need to know more about your computer and the images (resolution in MP), as well as your Task options to begin to guess if the time to process is normal. Just going to say that yes, it likely is just fine.

  2. It will use what it needs to, when it needs to. Also, there is a concept of commit charge that means that sometimes, you will need a larger pool of RAM+SWAP available than is physically in use at a time to prevent Out-Of-Memory errors. Many Linux distros kind of skirt this by allowing for Over-Commit.

Ram usage has a lot to do with image size and settings.

I have 64gigs and have a hard time getting real ortophotos, I usually just make a pointcloud and make a orto from that in CloudCompare.

Hi there!
For what it’s worth here is the system information. Pictures are 4000x2250 taken at 350 feet above ground with 80% overlap side and front. 170 images. But it sounds like this is fairly normal running time.
I had the resize option and the below options
Options: auto-boundary: true, dsm: true, dtm: true
