    Tested today, sent an image up to FOG compressed at level 6, Image is 40GB C Drive and 40GB Recovery Partition. Starts off at 4.5GBpm then steadys to 2.5GBpm. For deployment of this image back down to a client again starts around 4GBpm then slows to around 2.5GBpm, added 3 more clients and still around 2.5GBpm, im not at work at the moment so trying to get my colleagues to test and send me the figures over. Does this speed seem normal?

      @Huggybearjr For FOG 1.2.0, yes that seems about right. For FOG Trunk, this would be very slow.

      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!

        Its FOG trunk, svn 4363. avg speed to deploy with 8 clients is 750mbpm. The network shows the network cards as been 1GB cards, I/O of the raid seems to be fine, our switch is fine and tested. So much slower than our last build, but can’t figure out why? 😞

            @Huggybearjr Multicast or Unicast?

              Unicast, by ipxe booting first laptop then selecting “quick image” then selecting the image, then repeating until 10 clients are “quick imaging”

                @Huggybearjr Is there a bottleneck anywhere between the 10 clients and the server?

                A 100 meg link? a switch with a 100meg uplink ? Or even a bad fiber connection that has degraded to 100 meg?

                What speeds do you get on a single client if you connect it to the same switch that the fog server is connected to?

                  Fog server network card 82540EM Intel Gigabyte controller, into 24 port switch in which all the clients are plugged into. This switch and setup hasnt changed from the last setup which worked fine. Changed the cables, still the same. Would it be worth doing a read / write test on the VDI thats on the raid?

                    We are a rental company, so just have a small isolated network been the switch to image machines back to a standard image before going out to the next client. So not trying to deploy over a School IT network or anything like that.

                      Couldn’t hurt.

                        is there a reason you’re running fog on Ubuntu 12.04, inside a virtualbox VM, on top of a Ubuntu 14.04 server, instead of running it right on the Ubuntu 14.04 or on a proper bare metal hypervisor if you want it in a VM?

                          12.04 is really stable with 1.2.0 out of the box. Maybe he doesn’t have a Windows Server or VMWare and wants the security of snapshots still? But, you do make a good point. If the VDI speeds are terrible with this setup, might be best to bite the bullet and install on bare-metal 12.04 with 1.2.0

                            @Wayne-Workman I wasn’t questioning the use of Ubuntu 12.04. I actually still use it on my fog servers. my question was mostly regarding the rational behind the older-OS on VM inside newer-OS arrangement.
