I was burning a set of Slackware, Mandrake and AAv2.0 CDs for a friend today; I got lazy and decided to simply burn them off of the mapped drive, instead of transfering the .isos/directory trees over to the Local Hard Disk. I had done this before with very small files in Disc-at-Once Mode with 4x-8x CD-RWs, but never a full blown ISO, so I was curious. My network was robust enough: 100Mbps Switched, so I figured, what the hell:
The first one I tried was Slackware over the network at 12x (1,800kBps): Complete success.
Then Mandrake at 24x (3,600kBps): Complete success.
Finally America's Army 2.0 at 32x (4,800kBps): Total success.
The interesting things about the exercise was CPU usage: Most of the time, I'm hitting about 6-10% CPU usage Peak with an average of about 5% (regardless of CPU speed; 600MHz to 2GHz clock speeds the CPU usage stays about the same.) when making an Hard Disk to Optical Disc transfers on an IDE-based machine, as most of my machines are IDE in one form or another.
When using a mapped drive over the network, CPU usage dropped to 4% Peak, averaging about 1.5%. My Network usage never went above 40% of the maximum, and the machine it served from never went above 2% CPU usage (Running an IDE-Based RAID card).
I wouldn't be so comfortable with doing this in an unswitched network, but as it is now, I'm not going to shuffle files anywhere near as much as I used to. Old Habits die hard, and I'm making sure to well and truly kill this one.
