Blue Iris

My alerts list loads slowly, 7-9 seconds. It is slow even when I select a single camera. I have adequate CPU and RAM, never using more than 40% of CPU and 30% of RAM. (NUC i7 11th gen 64GB RAM, both drives SSD, alerts on C, clips on D, AMD GPU so BI doesn't use it). I think the problem is the sheer number of alerts in my data (71K), because if I condition on the past three days, or even 7 days, alerts load rapidly. I only use the default sort (by date).

Is there a way to default to the past N days? Currently I see a select for today, but in the morning I typically look over the night's video, which isn't all available under Today, and moreover UI3 forgets the setting when reloaded. The past 24 hours would work well for me as a default as I can always change if necessary. I would need the selection available in UI3.

I do have a lot of cameras -- 13 -- and I record 2K continuously but at 5 frames per second, and motion sensing on the second stream at 20 FPS and 640x480, so from BI's perspective, I have 26 cameras. This works great except for the slow alerts loading. The problem arose after I changed to substreams and reduced the FPS of the main stream, because I have more than tripled the number of stored clips in 2.5TB of storage.

Based on the lack of reaction, perhaps this should be a feature request -- the possibility of setting a default of "Show last two calendar days" which the user can override if desired.

I don't think 13 cameras at 2k plus duplicates at D2 is an overload for BI, although it seems to me as over-optimizing: I have 1080p substreams, and D2 substreams, and triggers switch to 4K on 13 cameras, and BI doesn't skip a beat on an old i7-4790k. So you probably have something else going on.

I noticed a dramatic performance improvement in all areas once I switched from H.265 to H.264. Could that be what you are dealing with?

Is the database rebuilt regularly?

I have the database compacted daily, but your message made me repair it, but that did not solve the problem. I agree that resources are not the issue especially because the problem does not occur even if I condition on the 3 days of clips, though if I go back a week, I have ~4 seconds to load, enough time that I see "Loading 3 days" before the clips appear. So it does seem to have to do with the sheer volume of clips.

Weirdly, the slow alert problem vanished recently. I've been on release 5.9.9.21 since 1/15, but I didn't notice a speedup until yesterday, 1/20.

I suggest checking AV exclusions as mentioned in the Help file.
