Performing state change on bulk configuration objects using iControl

Hi, I am trying to use iControl to do bulk state change. Currently I am able to successfully change the state when performing on one Virtual Server.

I found one API reference i.e. "LocalLB::VirtualAddressV2::set_enabled_state". In the prototypes I see "in String [] virtual_addresses" mentioned which I think means I can perform the action on multiple Virtual Servers.

I am not interested in knowing if my understanding is correct and how many virtual servers can the agent handle at a time. Also is it a sequential processing of all the paraments passed or its parallelly initiated to all the virtual servers.
