Multiple Coexistence Manager behind a loadbalancer

Hi there,

a customer of us is in the process of a Notes to Exchange migration. In general it is working fine, but the customer mentioned that the Coexistence Manager's cpu utilization is always to high due to the high amount of freebusy requests and mail flow between Notes and Exchange.

They already setup a second Coexistence Manager server, but the question is now, what would be the best practise to implement both together behind a loadbalancer?

Kind regards,
