I have various laptops in different rooms acting as DVRs. And what is
interesting about recording in the WMV format, as you can play it with
another application while it is in the process of recording by another.
Thus I can stream this video to any other computer on the (W)LAN. That
Although moving GBs from one computer to another in a speedy manner,
neither WLAN or LAN impresses me very much. Here I much prefer good old
faithful sneakernet. As it is so much faster. Has anybody else came to
the same conclusion?
Sure, sneakernet can be faster. A USB3 pen drive. ESATA SSD.
In terms of wired LAN, in my testing with GbE, I find some NICs (Intel
brand, Marvell, maybe a Broadcom) are capable of benching at 117MB/sec
out of a possible 125MB/sec. (I presume the difference between theoretical
and achieved, is header overhead.) I think at the time, I was using
something like "rcp" or remote copy, in an attempt to keep the
protocol lightweight. A number of years ago, my favorite method
was FTP for doing the testing.
I have one NIC though, with a RealTek chip on it (8169), which only
does 70MB/sec using the same test methods. After more testing, it
seemed to be quite processor intensive, and by extrapolation, would
need a Core2 processor running at 4GHz, to catch up with the other
I've heard, you can use "teaming" with NICs, to combine the bandwidth,
but I don't know if a single connection with a naive protocol, can
take advantage of both NICs at the same time. That would mean using
more than one Ethernet cable between computers. I've never tried that. While
I have motherboards with dual LAN, they're using different brands of
NIC1 -------------- NIC1
computer NIC2 -------------- NIC2 computer #2
There are some near field wireless technologies (UWB), that could probably
beat all of that, but they're quite restrictive on usage. That would
probably work, between two computers in the same room. Once you
move away a bit, throughput drops to more "normal" (i.e. useless) levels.
In this graph, you can see UWB and Wifi compared, The FSO in this graph,
is free-space-optical, which would be line of sight only and would
not pass through walls. For generic wireless operation, Wifi is
cheap and most likely to do a little bit for you, within the
There's always ten gigabit Ethernet, but the price still isn't
low enough. You'll need a good slot in the motherboard, for one
of these. I like how I can't find any customer feedback
for these products
Just too expensive.
I presume that's using a PCI Express x8 interface. You may not have
enough good spare slots to add it. (There are a few commodity
motherboards out there, with x16 plus x4 for example, and the
video card would take the x16 slot.)
For a price, I'm sure someone offers faster than that.
If you try hard enough, you may be able to engineer a situation,
where the storage subsystem can't keep up.
