...and the answer seems to be: nobody knows.

There are ways to group virtual/real server definitions in both
keepalived and ldirectord, but when you get to the bottom line you're
still talking about 2200 realservers needing to be checked.

I think the only way we're going to bottom that one is to try it. I dare
say that it's possible, but managing the latency and memory requirements
of something like ldirectord forking 2200 check processes is going to be
rather tricky. Not to mention the startup time!

How well do your hardware devices handle this? Do they check all 2200
realservers successfully, and if so in what timeframe?
