Description
Setup:
- two Xeon boxes
- one Intel X520 10G-base-T NIC (ixgbe driver) in each box
- a single CAT6 cable to link them
- DragonFly-3.1 server
- Linux kernel 2.6.32 client
NFS/TCP file transfer performance only reaches 450 KB/s top
The same Linux client machine is able to read files at a speed of 110 MB/s using
regular Gigabit network interfaces (bce and em drivers)
