How many ports == "LARGE INSTALLS"?

Whenever mysql becomes the bottleneck due to your different running pollers fighting for it. I'd say, for 8 or more concurrent pollers. But we don't really have a lot of data from people with such deployments.

What sort of data are you looking for? I don't know a lot about MySQL performance tuning, but i've recently had to move to more than 8 concurrent pollers on at least two different sites.

runtime stats from observium.log from before and after setting $config['slow_statistics'] = FALSE (and/or enabling memcached, but that will slow things slightly after removing slow_statistics)

Installs where people are having performance issues, notably MySQL locking.
