Corosync was not tested in 10Gbe environment (with exception of IBA).
And honestly, I don't think 10Gb can be achieved with standard MTU. So
my adovise would be to try increase MTU of NIC and then increase MTU in
corosync.conf.
I use both 9000 and 8982 MTU, the performance is almost the same.
Also corosync 2.x contains many optimizations so it can behave better.
