Assuming this dd was run from one of the servers to a replica 3 volume,
you have one localhost write and two network writes for 88 Mbit/s which
looks like the maxing out of a 100Mbit connection. That is so
coincidental it would lead me to look at the network.

Now i'm using a bonded gigabit (2x1GB) on every server but i'm still
stuck at about 15-30mbit/s when extracting the Linux kernel. Total
extraction is still about 10minutes.
Something strange is going on, on a dual gigabit connection (2000mbit)
I'm expecting to reach hundreds of megabit (200-300), not tens (15-20)
# dd if=/dev/zero of=/mnt/glusterfs/zero4 bs=1M count=1000
1000+0 record dentro
1000+0 record fuori
1048576000 byte (1,0 GB) copiati, 88,2981 s, 11,9 MB/s
No suggestions?
