If the same image must go to each computer, you could use multicast.

You did not say anything about which OS you were using, or about the architecture of the systems involved, or about how you measured the throughput. 240 Mbps is not too different from what I would expect from a standard PC running Windows: to go faster, you need a better-designed architecture. I would suggest that you look on tomshardware.com for the article about gigabit networking,

So, you are going from filesystem to filesystem (perhaps disc to disc) and getting 30 megabytes per second. What is your local disc performance? If it is around 30 MB/s you have found your bottleneck.

Or, use something that does not involve the filesystem - eg

We are using Dual Xeon 3ghz computers with Windows XP Transfer is done Camera -> DMA -> Memory -> Clients Clients will process the data and dump it.
