Works great for me - I have an 16TB LTS NVR that records my 16 LTS cameras 24/7 and use BI as a camera front end for my home automation system and mobile viewing; neither miss a beat. The NVR and BI PC both have Gbit LAN, and all my switches are Gbit so there are no network issues (cameras are only 100Mbit, of course, but they add up when streaming to 2 servers and you add in other network traffic). My NVR monitors the main stream and BI Monitors the sub stream (none of my BI clients need HD streams).
