Performance - andyj - 06-27-2019
Hi all
I've got OAP running on a 3B+ with the official touch screen. I've noticed that performance is degraded significantly when running something like the web browser and wondered if there's anything I can do to mitigate this? Are there processes that might get run by default that could be closed?
I tried running RPi Cam Web Interface to build my reversing cam but it's so slow it's unusable.
Just as an aside, I added a button to the applications dashboard that runs raspivid - t 6000 so you get the camera preview over the top of OAP for 6 seconds - probably enough to check how close you are to the car behind. That seems to work really well so the lag doesn't seem to be the video processing but all the stuff necessary to run RPi Cam (Apache, php, etc).
Cheers
Andy

What is your CPU and RAM usage?
Please keep in mind that there is 1GB of the RAM and 1.4GHz CPU. You can easily be out of enough resources.

So presumably it will do better on the pi4 with say 4gb of ram?
I would love to know more about your setup, Andy! I badly want to use an IP cam as a backup camera. Aftermarket backup cameras seem to have poor video quality. Limited by the analog signal.

Hi
I don't think there is anything clever about my setup. I'm really only just starting with this. I've done lots of other Pi projects but this is the first carputer. At the moment, I'm using a V1 Pi camera with the ribbon cable while I'm playing. When I get to the point where I can put the camera on the car, I'm planning on using the Pi Camera HDMI extension kit as I think an HDMI cable in what is quite a hostile environment will be better.
I'm probably going to be in a position to get the Pi in the car at the weekend to test whether everything works in principle. I'll keep you posted
