Ahh. That's good to know. I'll disable them.If you are not recording continuously, then no need to record dual streams and then as you said the pre-trigger works...

OK, so I DO want that feature. So that's probably the reason it's enabled by default.If you want to use the timeline to play back multiple clips at once, then it becomes very important to have the sub stream recorded so it doesn't have to play all main streams.
Total cpu is typically around 5% with BI taking 2.5%. That's with 14 cameras. Of course it used to be 25% with BI4.If you have enough free CPU time, you can still do timeline playback with only main streams. That is how it worked for years before sub streams started getting recorded. But even if it works with main streams, seeking should be a lot more responsive with sub streams available.
HA?You could also try shutting off HA for that camera. It won't have any real impact on CPU utilization.
