Ignoring filtering, is there any idea roughly how many persistent 
replications can be running before it starts to hurt performance. I know 
this is a vague question, highly dependent on the system resources of the 
machine hosting the database, the number of updates being made, etc. I'm 
just trying to get a rough idea if possible. Are we talking like on the 
order of 100 replications, 1000s, etc?
