Mirrormode - active/passive fail over. Only writes and other various meta properties will get to the active master.
The other node is a failover - ideally you shouldn't be making any writes to it that would normally go to the primary.
As for load, etc, the site I manage has a pretty small directory, so I can't offer any useful data.

Dear Folks,
We are setting up mirror mode masters with eight fairly heavily loaded slaves (consumers).
Should they all slave from both masters?
An alternative is to slave from one, where a floating IP address is that of "the master".
Please can anyone share their experience?
Would all slaves being consumers to two masters result in any marked increased load on any of the servers? -- Nick Urbanik http://nicku.org 808-71011 nick.urbanik@optusnet.com.au GPG: 7FFA CDC7 5A77 0558 DC7A 790A 16DF EC5B BB9D 2C24 ID: BB9D2C24 I disclaim, therefore I am.
