The queues should have appropriate memory limits for the given number of NotificationDispatcher MDBs and number of tokens loaded in one batch,

we want to optimize these variable properties:

• number of senders (MDB's maxSession=<#SENDERS> activation config)
• batch size (sender configuration via env properties)
• number of batches to be loaded in one cycle/transaction (sender configuration via env properties)
• memory limits for the token queue (hornetq's queue: max-size-bytes=<BYTES>)

the properties that are "known" (i.e. can be measured/tested):

• size of the message in token queue (specific for each variant) (hornetq's queue: min-large-message-size)
