BI delay

[rldun]

I have a server with 38 cams. Averaging 19% CPU and 6.69 GB RAM and I have a 3 to 7 second delay in everything I do on the server. Any click, typing or other action. I have disabled cams 1 by 1 and it continues until I disable the last cam then it runs perfect. As soon as I re-enable any cam it is back to the delay, does not matter which cam it is. Here is some of my specs and I am truly stumped. I have update BI, all firmware, windows updates, BIOS with zero change.

Not the best processor for Blue Iris, but......
Be certain you have performed every step listed HERE.
Pay close attention in how to exclude Blue Iris from any and all virus protection, including MS Defender, as outlined in the Blue Iris help file.

Use substreams if not already. Sub Stream Guide

Forgot to add I had disabled AV completely to test if that was the cause with no change. Also running substreams on all camera

Some of my settings. I am trying to tweek this for a good quality recording as well as smooth running system. The more I read the more confused I get as people have valid arguments on encoding type, fps, bitrate and such. This customer is a church and these set of cameras watch the nursery rooms, kids, church and inside of the building. They are continuous record with triggered saves.

Camera settings.
H264 or h264h
Iframe interval set to 15.
Bitrate, set to 8192 or higher for mainstream, and 1024 for substream.
Set combine or cut video to 1 hrs.

I will give these a try, but I have a question. I thought H265 was supposed to be much more cpu friendly than 264, is that not the case?

BI can struggle with H265 as some manufacturers play with the codec, but it takes more camera CPU to process H265 than H264, so some cameras struggle. Just because they offer H265 doesn't mean it can do efficiently.

Most here run H264.

What is the advantage/benefit for setting this down from the default of 8 to 1 hour??

since you run a server os => make sure that you adjust the cpu scheduler:

Easier to manage viewing clips if you only have to handle 1hr clips vs 8hrs.
8hrs is fine if you only record on alerts, but continuous recording is a different beast.
