Hi All, I'm trying to figure out why Blue Iris is using so much CPU. Just to dispell all of the usual suggestions, here's some info about my setup. I have 12 Hikvision cams, all at 10fps. They are spread across 3 POE hubs, each of which connects to a different port on the same gigabit switch the server is connected to. Nothing else but cameras and the server is on this switch. The 64bit version of Blue Iris is running on a 64bit version of Windows Home Premium, on a 64bit Intel i3 3Ghz processor with 8GB of RAM. Nothing else is running on that system: just the OS and Blue Iris. The camera are all set to record Direct-to-Disc. Motion Detection is being done on the cameras themselves, which trigger Blue Iris when there's motion via ONVIF triggers. The vast majority of the time, the console isn't running, so no views are being rendered. Literally all that Blue Iris is doing is chilling and waiting to be told to record when a cam pics up motion. So why is the Blue Iris thread constantly at 48-55% CPU load? That's very high for a system that technically isn't doing anything. Logging in via console or web browser will push CPU usage to between 70-80%, presumably from rendering the multicam view, but being at such high CPU usage makes the interface sluggish and frustrating to use. Despite 8GB of RAM being available, it only seems to use around 1.2GB. Any ideas? I'd really like to solve this, because I like Blue Iris. I've been doing experiments running ZoneMinder in a VM on my desktop, and even running in emulation it's able to handle all 12 cameras with no effort, so, I don't get what's wrong here. Any suggestions would be greatly appreciated.
