know from previous experiments that my hard drives and general system
throughput can handle about 25MB/sec.
If you are seeing 10 MibiBytes per second on a 100baseT, you effectively
have no network traffic on it. Must be nice. That's one reason why you
are seeing practically no increase.
This is my home network, with currently only two machines running. But I
would have expected to about double my transfer speed based on my
current system capabilities.
Second, I think you need to bump the default TCP packet size. On a
network that small, the TCP window is probably filling and throttling
the transfer rate.
Make sure your systems are sending 9000+ byte packets rather than just
1500+ byte packets.
OK, off to the man pages to figure out how to do that.
