Download Speed - Can it be improved?

[Chris Shanks]

Afternoon all,

Tried to find a coherent thread for things to change to try improve fog speeds but haven’t been able to find anything concrete.

All of the images I am pulling are around the 30Gb mark.
Running fog svn on a virtual os.

Right now I am pushing an image to a host and getting around 3.3Gb/minute (400Mb/s). In the past I have seen this up at 6Gb/s but I would like to achieve 1000Mb/s per host being imaged.
Network card is Realtek RTL8169/8110 family PCI gigabit ethernet NIC
Running through either a gigabit TP-link SG1024D (probably has a small backplane) or I have a cisco SG300-28 which has full 1 gig duplex capacity on all ports.

I have upped the MTU of the port to 7000 and the port is running on 1000 base, full duplex.
The image data is being pulled from a Raid5 4-disk array which I thought the read speed may be the problem?

Any other thoughts or tips to improve speeds?
Thanks,
Chris
