Tim is correct. For some more details, have a look at the section in the 6.4 user guide that covers HA heartbeats:
The inter-controller heartbeats only apply when using the new high availability models of 6.4; not traditional primary/backup LMS or VRRP primary LMS based deployments.

Is it subsecond in total or only for the AP's?
Example: a controller, with 1000AP and around 3000users, fails and this HA feature is used, would all these be on the backup controller within 1 second?
Are there any test beds performed on this feature?

- The intercontroller heartbeat between the standby and the active controller occurs every 100 miliseconds
- After 5 missed heartbeats the standby controller will ask the APs to fail over to the standby controller
- How long it takes for the AP to failover is usually a second or less.
- Users get disassociated from the AP when this happens and they have to reassociate after the AP comes up on the standby.
- How long it takes depends on the client, more than anything.
