It really depends on the load on the machine, I guess. In practice I've not seen more than about 15 records per iteration for a desktop machine. I can image that growing quite a bit on a busy multi-user server.
As far as I know, if the buffer is not big enough, events will simply not be written, so for my application I'd rather use a bit more memory and rest easy that I'll catch all events.
