Performance Issues After Increasing Ram and/or Software Updates?
Posted: Wed Jun 26, 2019 3:17 am
I'm running Ubuntu 19.04 with seven Reolink Reolink cameras consistently for the past 6 months. I'm running version 1.32.3 of ZM. This machine strictly runs ZM headless and nothing else.
Prior to a few weeks ago, I was seeing CPU loads around 7 to 8 on average on an intel Xeon machine that has 12 cores. My shm was hovering around the 75% with 16 gigs installed and so I decided to double the amount of memory by throwing in another 16GB.
Before turning the machine off I updated all of the software and then shut it down. After installing the memory, and starting up ZM, I'm now seeing CPU loads anywhere from 9 to 12 (see below) and I can't determine why the increase in CPU load is now all of a sudden there after only performing software updates and increasing the amount of ram and without changing any parameters in ZM.
I've turned off all of the cameras and slowly added each one back in to see if it was a single camera that was causing the issue, but the only thing that I seem to notice is that after adding a fifth camera CPU usage seems to jump. It doesn't matter what camera I add before seeing the jump so I don't see a correlation there.
So, my questions for the forum:
1. Are there any camera settings that would be impacted with the increase of system memory? If so, what would those be?
2. Is anyone aware of any Ubuntu, or Linux, recent updates that would have cut the CPU performance of the machine.
Thanks in advance for any feedback.
