Slony - Wait for Event

What is the behavior of Slony waiting for an event after lock set command? Basically I am trying to do a switchover and it takes a lot of time. We are following these steps: 1. Lock Set 2. Wait for Event (timeout = 300) 3. Move Set (timeout = 300) 4. Wait for Event (timeout = 300) The alt perl script we have with Slony source has the following sequence: 1. Lock Set 2. Sync 3. Wait for Event 4. Move Set What should be the correct sequence of events and how can I make the switchover faster?
