Hi Florian,
why improves bonding of the replication-connection not the performance. We currently have a direct connection for the 1 Gb DRBD replication and I wanted to activate an active-active bonding (with a further LAN-port). I would expect nearly double of replication-performance. Andreas Kurz had spoken at a workshop for that. Or depends it on whether the connection between the nodes directly or via 1-n switches. regards "Florian Haas" <[email protected]> schrieb im Newsbeitrag news:<[email protected]>...

TCP reordering is definitely going to kill you. This is expected to have lower throughput that a single non-bonded link. Remove that bonding configuration. Then re-run your tests. If you want higher throughput than about 170MB/s over the wire in any single TCP connection, get 10G Ethernet. Or Infiniband. Or Dolphin Express. Bonding isn't going to help you.
