Yes, depends on the amount of things you handle with it and how your
machine can handle it.

The amount of folders will impact memory consumption (and storage). The
number of filters potentially impact cpu cycles (and a bit memory).
There is no real limit for all this, neither by design nor by
experience (there could be, by internal data storage types and other
platform specs but I guess any user is really very far from reaching
the boundaries).

Here: 2 instances, ~30 accounts, ~450 filtering rules + ~250 folder
processing rules (almost all active, CM could manage way more filters,
would only cost cpu cycles when they are fired), ~750 folders,
1,200,000 messages. 5GB virtual memory + 2GB resident for the biggest
instance. I would not run this configuration on a low-memory system,
slow cpu and disk, though, but I would definitely not run other email
software in weaker conditions (and not even w/ how much data).
