Oh, and I see you are pinging via ipv6, that is another variable i've never tested with - if you have ipv4 addresses can you be sure gluster is using them? If ipv6 isn't native on your network is a router/other box running some kind of ipv6->ipv4->ipv6 thing and slowing down everything?</div>

I'd try putting all hostnames in /etc/hosts. Also, can you post ping times<br>
between each host ?<br>

They are in /etc/hosts.<br>

As said before, I don't think there's a problem with the LAN. Trust me, I would know about it :)<div class="HOEnZb"><div class="h5"><br>

Ah... are these nodes separated by a WAN? Synchronous<br>

No, it's a 1 Gbps LAN. The other "site" is within LAN-range.<br>
