Here's a month's worth of tuning on this machine, which is still 12 720p Cams at 6fps modect; I upgraded the ffmpeg to:

ffmpeg version 3.3.4-2~16.04.york0 Copyright (c) 2000-2017 the FFmpeg developers
built with gcc 5.4.0 (Ubuntu 5.4.0-6ubuntu1~16.04.4) 20160609

but the load is still 9-12 idle recording, and jumps to 16-24 in Montage Live.

-------- Recommendations ---------------------------------------------------------------------------
General recommendations:
Control error line(s) into /var/log/mysql/error.log file
Variables to adjust:
query_cache_size (=0)
query_cache_type (=0)
query_cache_limit (> 1M, or use smaller result sets)
innodb_buffer_pool_size (>= 615M) if possible.
innodb_log_file_size should be (=16M) if possible, so InnoDB total log files size equals to 25% of buffer pool size.

General recommendations:

Variables to adjust:
query_cache_size (=0)
query_cache_type (=0)
query_cache_limit (> 1M, or use smaller result sets)
innodb_buffer_pool_size (>= 615M) if possible.
innodb_log_file_size should be (=16M) if possible, so InnoDB total log files size equals to 25% of buffer pool size.

General recommendations:
Control error line(s) into /var/log/mysql/error.log file
Variables to adjust:
query_cache_size (=0)
query_cache_type (=0)
query_cache_limit (> 1M, or use smaller result sets)
innodb_buffer_pool_size (>= 615M) if possible.
innodb_log_file_size should be (=16M) if possible, so InnoDB total log files size equals to 25% of buffer pool size.

You are still running a 32 bit OS. Did you try the other machine with a fresh install of Ubuntu 64? I suspect with the 32 bit OS you are getting a lot of buffering/swap that is slowing things down and possibly not using all the cores on your processors.

I'm using about 60MB of swap atop 6GB of physical RAM; free says 1.8GB or so available.

And the other machine, alas, is having disk controller problems, and I haven't been able to get it to boot.

That said, I would expect *less* trouble with the 32-bit install, since the binaries are half the size. No?

No. MYSQL will hit memory limits sooner. Search for yourself. 32 bit systems should be used for light loads. I set up a Ubuntu 32 bit system tonight on my one camera i3 with 8 gig of RAM and noticed it did not work as well as a 64 bit system. Ubuntu 32 bit OS will set up PAE to use memory above 4 GIG but programs will still be limited to 32 bit memory limits. You would be best to dump your zm database and save the zm.sql to another drive, load the machine with fresh 64 bit OS and set up ZM. Clean out the ZM database then import the saved sql. You will loose events but keep the camera settings.

I setup 12 ipcam in ZM_1.30.4 on a debian9 vm into esxi6.5. VM dedicated RAM is 8GB. CPU is Xeon E3 1246V3. Disk controller is LSI megaraid 9271-8i 1GB cache. DB is MariaDB, with some changes in cnf file as well as suggested by mysqltuner.
10 cameras are running at 1280x720 @ 25fps and 2 are running at 1280x960 @ 10 fps. Totals fps is 270, so much havier than your setup!
All monitors are in mocord mode.
System load at idle is 4.5 and with several alarms does not go over 6.5.
I experienced high load if in the options->Images->JPEG_FILE_QUALITY and JPEG_STREAM_QUALITY, you set too high values. I got good results setting them at 80. After changing it, restart ZM.

Ok, well, sure, bbunge, but MySQL says it's good up over 2GB, IIRC, and I'm peaking it at 500-something MB. Or did I misread the report?

I don't particularly mind the exercise, but the bigger the hill it is to climb, the more justification I like to assemble for doing it, and I don't know that I'm there yet.

Is there any way to do any system-level profiling to prove that "mysql is slow returning to ZM" is the place where the load is running up?


And to jbg70: you're in mocord, so in theory, at least, you're not doing any motion detection; that can be a big piece of the puzzle, I would think. I do appreciate the report, though, and I'll check the JPEG parameters.

I think I'm also going to do the Maria swap-in.

Mocord is continuos recording + motion detection.

D'oh. Yep, was thinking nocord, obviously.

I see I never followed up on this.

I ended up replacing the box with the 4-core i7 it should have been in the first place; I now idle at .8 and don't break 4 with a 12-camera montage review up.

My thanks to all the people who contributed.
