We transfer images from a host computer
to 5 client computers , each image is 1024x1024x8bit=1mb
what would be the fastest way to transfer this data ?

For now we use Gigabit ethernet , we get net max 30 mbs (mega byes/sec.)
using TCP

You need to specify the volume. For some types of data transfer a truck is
the fastest means (never underestimate the bandwidth of an 18-wheeler full
of disks--the latency's a bitch though).

Broadcast and UDP if occasional errors (snow) are tolerable.
If the machines are fast enough, compress data, but the snow
gets larger. Which compression depends on image type.

This sounds very typical for a PC with a standard PCI bus.
You need 64 bits or 66 MHz varients of PCI to go faster,
even though the theoretical max of PCI is 133 MByte/s,
there's a lot of overhead for short bursts.

We transfer None stop 1mb chunks
from the Host to the clients
The host queues the files and transfer one after the other
to the clients.

So the host sees actualy 30mbs & client 30/(num clients)

Look into broadcasting or multicasting, then you'll transfer to all
the clients in parallel.
