Re: Painfully slow performance

The voltage measured over the GPIO pins is >5. I am going to try a bigger power supply though. I can get a 12v - 5v/3a dc to dc transformer which I was going to use as an in car supply anyway so maybe that will help. The problem is not heat, the sensor reads <50. The board does smell bad though, I m...

Re: Painfully slow performance

If you just run a browser on a Pi3 and nothing else and don't go onto complex websites then I'd say 50% of people would say performance is acceptable Once, you deviate from a simple requirement like that, things are just going to get less acceptable So its easy to see how running nodeRed and a brow...

Re: Painfully slow performance

Sure enough, it appears to be stuck on 600mhz, even though CPUFreq front end frequently says its gone up to 1400, or whatever. How do we fix that? For what its worth, I'm running on a usb power pack now and no longer have the voltage icon in the top right, although the red light is still a bit flick...

Re: Painfully slow performance

I have tried overclocking but to no avail my PI also stinks of electrical burning ! Could the two be linked with your slowness? Is it damaged and now throttling down? Someone here can probably tell you how to find out. I don't think so, it smelled straight out the box. Have you actually checked the...

Code: Select all

sudo raspi-config
Go to advanced options for the experimental driver.

I remembered as soon as I posted. Which option is the experimental one? Full KMS or fake?

Re: Painfully slow performance

Did you try enabling the experimental graphics driver ? You are running the latest image , aren't you ? ghans Everything is as up to date as can be. I haven't enabled the experimental driver, do you have details for that? I suspect this is simply a problem with the code you are running requiring a ...

Re: Painfully slow performance

Don't get me wrong I'm not expecting a speed machine and I won't be using it to browse (like I am now) daily but if it can't display a simple set of gauges in a browser then it is of no real use to me. It's just taken about 3 minutes to log into Facebook, with extra time on top for it to open a mess...

Re: Painfully slow performance

Oh, I should mention my PI also stinks of electrical burning ! Do you have a heatsink? Fan? If you are running it hard, she will get hot and throttle CPU speed. No heatsink or fan, its a new out the box board, a day old. vcgencmd measure_temp returns 45deg, despite clocking Which browser ? Any! Eve...

Re: Painfully slow performance

3b, connected to hdmi. It freezes and stutters a lot generally and as above, an animated dashboard which equates to about 4 gauges (https://canvas-gauges.com/) in node-red-dashboard is basically unusable. It seems to buffer all the data and then play it back, which over time means the delay gets lon...

Painfully slow performance

Has anybody come up with a way to overcome this yet? I have tried overclocking but to no avail. I bought the PI to set up a node-red-dashboard and small display in my car but it is so slow that the dashboard is unusable. General browsing is also ridiculously slow and clunky, and anything animated is...

USB boot, rpi 3b

Hi, this is my first Raspberry Pi and it is completely refusing to boot from USB (I can't find my microsd adapter). I have done the program_usb_boot_mode=1 routine and checked the vcgencmd otp_dump | grep 17: output, which is correct, but it has made no difference. If I try to boot a stick (I've tri...
