    Hi,

    Specs :
    Ubuntu 12.04 (VM via VMWare)
    1 Single Core i3 CPU (just for now, gonna upgrade if needed)
    1GB RAM
    200 GB SCSI HDD

    Image :
    2 Partitions :
    One 140GB partition on a 450GB total disk
    One 10 GB recovery partition (maybe I should just no touch this one at all but I’ll figure that out later)

    I’ve been trying to use FOG for a few days and I’ve run into a problem.

    After finally being able to set it up and upload my image, I just tried to deploy one today. Deploy was ok running over 1 GiB/min (pretty slow I think ?). I thought i’d let it run during lunchtime but when I got back (2 hours later) it was around 55% and around 400 MiB/min (constantly decreasing).

    Checked on the web interface, at first it was a constant 10MB/S traffic on the graph, now it’s oscillating between 0 and 2 MB/S on and off.
    There’s nothing happening for a few second, then there’s a 2MB/S bump, then nothing again etc…

    Network’s not bloated, we dont even have 50 workstation on the network and no important traffic going on.


    Did I forget to do something or maybe did something wrong ?
    I’ll try to debug this tomorrow but I figured maybe it happened to somebody already. Been searching the forum and the web, saw nothing remotely similar to this.

    Do you have any ideas ?

    Thanks 🙂

      I don’t think this is an issue with the interface. The image you’re trying to upload is coming from a VM or a physical host? I’d try uploading an image from a physical host just to see if that has a decrease in speed as you’ve described. I’ve seen speed issues when imaging to/from a VM whether VirtualBox or VMWare. It’s just not as fast.

      Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

        I’m pretty sure it’s not either but I just don’t want to miss something.

        If it was constantly that slow yeah, but why nothing going on for a few seconds then a bump ? And why did it work 4/5 times faster at the start ?
        If I had to wait 30/40 min to image a computer frankly I wouldn’t mind. But now it’s been imaging for 5h40min and it at 87%. I’ll just let it finish to see it it atleast works.

        I would like to get it running pretty well then maybe think about getting it setup on a physical host, but we don’t have any to spare right now so it may take awhile to test it.

        Anyway, thank you for your input, much appreciated 🙂

        Edit : Here’s a capture of the traffic on the web interface : [url]http://i.imgur.com/bqWRgik.png[/url]

          I don’t know what is causing the slowness between vm and fog imaging, but that’s what I see as well. I’ll see it start out, not fast, but not slow, to almost a crawl. I, too, only have vm’s that I can use to test so I’m much in the same boat, though when I deployed my wife’s laptop, it was not slow at all. Imaging was around 2.5 ~ 3.5 GiB Min on upload, and deploy was close to 4.0 and 5.0 GiB. I have gig switches at the house.
