I am currently using Fog 0.27 running on Ubuntu 9.04 installed an a VMWare Virtual Machine using 10/100M switch based network infrastructure. When uploading or pushing images I am getting around 400-450MiB/min (26.5GB image takes around 1 hour) is this about average for this type of network? Would moving Ubuntu/Fog to a dedicated computer increase this transfer rate any more? Other than replacing all our switches and nics to GBit is there anything else I could try to optimise the transfer rate?

Im running a 1gb switch with 1 lan cable and get just under a gig a minute on a 2.5gb image. When i image about 6 this goes down to about 100mb each...some lower

I have a similar setup using XenServer running on gigabit but a handful of machines image in 20 minutes or so.
What else are you running from your VM box?

For fog it normally takes around 30-40 mins to grab our images (which are in the 8-10gb range) and then around 15mins to deploy them to 15 machines simultaneously. Haven't got around to playing with multicast yet
This is all on a gigabit switched network with Fog running as a VM within our XenServer farm. If it's just deployment you want to speed up have you considered adding a storage node or two? Having a couple of storage nodes spread around can help to spread the load over a few more servers, and depending on the client connection limits you set possibly increase the number of PCs you can image simultaenously

We moved our FOG server from Virtual to Physical (as the good people at FOG recommend) and did notice an increase in speed - 50% or so faster IIRC... Our base 10Gb image takes less than 10 minutes now... Gig backbone with 10/100 to desks...

i have a hyper v server with a quad port gb nic Bonded to 4 GB
i get 985mb a sec data rate restore on 1 pc.
But i do all the pcs at once all 30 in 45 min.
