We are looking at setting up a new SQL Always On Availability Group environment for SQL Server. We are wondering if there's a difference in CPU usage of a synchronous or an asynchronous node?
Also one of my colleagues is saying there's a limitation in the number of Listeners (and so also AG's since it's adviced to have a listener per AG) but i'm not able to find anything that says that you shouldn't create more than 10 listeners in an environment. The only thing I'm able to find is that there's an AD-setting that you have to change to be able to have more then 10 listeners.
Thanks in advance!
