With your equipment you should be able to fill the cable to capacity and therefore your transfer speed should be somewhere around 100MB/s. Alas, the culprit could be anywhere and you will have to sieve a lot of dirt until you find gold.
Some possibilities, off the top of my head:
- check port parameters at the switch ports and network parameters of the interfaces: are they all at 1000/full duplex?
- have you enabled RFC1323 options? You need that for anything faster than 10Mbit/s.
- are your network buffers (tcp_receive_buffer, ...) big enough?
- did you mount one of the involved filesystems with concurrent I/O? This would bypass OS read/write buffering.
- what is the machines load? If heavy swapping is going on it might slow down all the other tasks too.
I hope this helps.
