hello

i am just a begineer 

i have made an experimental 2 k7 cluster, but i am having networks
problems because my latency times are really big (on the order of 1100
microseconds) 

as this cluster is experimental, i am interested in some
network interface that could deliver me low latency times (perhaps
gigabyte ethernet?, 10-20 microseconds?), low number of conexions (less
than 5 ports) and low cost (i pay the hardware, not my institution)

somebody could give me some advice ? is possible to join together:

- low latency times ?
- low number of ports ?
- low cost ?

thanks a lot for your help
