We're trying to decide if we should use a single large instance of SQL Server or multiple instances on the same server. This is for a dev environment.So far, I have these things to watch out for:Have to limit max RAM per instance so no instance grabs it allThere will be I/O contention and CPU contention between instances since the different instances won't coordinate with each other.It limits the available RAM for In-Memory tablesIt sets lower limits to the amount of RAM available for any given query, causing artificial "contention" even when there's nothing else running at the time.Anything I'm missing?Anyone have strong feelings for or against?
