Err, you mean the maximal mirroring speed ? (that is, after erasing the
default '25000' value in the interface, and the default '10 connexions' in the
connection limiter) ?
There are no other limits built-in in the engine - the speed is variable,
mainly depending on I/O's (network, disks) performances, and the engine
scanning capacity (which should have improved greatly in recent alpha releases
:p)
