Wow, that doesn't sound right! I have a gluster cluster at home using old P4 hardware, and cheap soho off the shelf gigabit switches, and I can get ~35MB/s writes with dd: dd if=/dev/zero of=/vol/scratch/foo/test.img bs=1M count=64 64+0 records in 64+0 records out 67108864 bytes (67 MB) copied, 1.76719 s, 38.0 MB/s dd if=/dev/zero of=/vol/scratch/foo/test.img bs=1M count=1024 1024+0 records in 1024+0 records out 1073741824 bytes (1.1 GB) copied, 29.3242 s, 36.6 MB/s And that's with no tuning of gigabit, i.e. no jumbo frames or anything, everything is stock, and off the shelf. One of my machines might even be using an old pci 33mhz bus cheap realtek gigabit card. The above numbers were on a straight distribute between two nodes, 1 brick each. On my other volume that's doing replicate between the two nodes, I get about 18MB/s (same hardware as above).
