Hey Folks...Happy New Year to all!
Got myself a new rig for Xmas and I wanted to see how BI would perform on this new monster CPU. The Intel Core i9-7980XE is by all accounts severe overkill for most applications. But during my last upgrade cycle (about 2 years ago), I went through the same process with a 10 core i7, and noticed that increasing the number of cores dramatically increased the number of cameras I could efficiently run on my system. At the time, I was running about 18 cameras and the i7 could run just fine at about 60%. So I started adding more and more cameras until I reached my current number of 33. But by then, I was forced to use the "limit decoding" feature on about 15 of them, to keep the CPU load to a reasonable percentage (it was consistently running at 95% before utilizing the limit feature).
So....fast forward to today. I just got the new system up and running...and to my pleasant surprise, I am able to run at full frame rate, all 33 cameras, and with a fairly consistent CPU percentage of around 75%. Some times it will spike into the mid 80's but it settles back down again after a short time.
A couple of other data points:
Of the 33 cameras currently running, 11 of them are 4K and to my thinking are responsible for quite a bit of the CPU load. I noticed measurable spikes in CPU load each time I added a new 4K camera.
One more thing worth noting....these i9 processors run HOT! And I mean...Mucho Caliente!
I had purchased a pretty beefy water cooler setup to go along with the new processor, but it was just not up to the task, so I had to buy a monster 6-Pipe Dual Tower Heatsink from Noctua to keep the temps at acceptable ranges.
To be honest, I was hoping for more headroom than this...but if I really want to, I guess I could go back to utilizing the limit feature if I want to add a few more cameras. But this is not ideal as the limit feature does not work when using the Web Interface to view the cameras. I guess time will tell whether or not I've reached the practical limit in the number of cameras I can use. 33 is a lot, but I'd love to be able to add more!
Anyway...I don't claim to have any "scientific" statistics or extensive tests to offer up, but thought that some folks might find this at least interesting to read.
Cheers everyone!

So yes I DO get outside! In fact for all the far perimeter cameras, I had to trench, lay conduit, and wire for power and Ethernet to allow me to get views of the property quite far from the house! Was a hell of a lot of labor! But still fun and quite satisfying now that it’s all done! 
I’ve learnt from the guys here that in most cases it’s pointless.
