My piholePi seems somewhat slow.

  • It is a Raspberry Pi 2 Model B Rev 1.1, so 4 cores @ 900 mhz.
  • Runs Pi OS Buster
  • Running the Pi OS Lite version

Here is the general load, of top -d 10

enter image description here

Sometimes, even opening a flat-file with vi (vim) takes 3 seconds or more!

I have a MicroSD from 128 GB in it, only one partition.

Would it help if I created 1 partition for the OS, let's say 15 GB, and the rest for data, and mount it under /data or so?

Do you know any benchmark-scripts anyway that I could run for analysis?

Thanks all!

top -d 10 output of 2 older and much slower Raspberry Pi "1" Model B Rev 2:

    You could just check top to see which processes are currently using most ressources. Anything that pops into your eyes there? – FelixJN Dec 22 '20 at 8:18
  • Done this, and it does not show anything I recognize as strange. I have updated my initial post. – Adriaan Dec 23 '20 at 10:39
  • SYSTEM CRASH: I ran rpi-benchmark on 3 pi's, 2 x model "1" and 1 model "2" On the model 1 it ran OK. On the model 2, it crashed my system. It ran OK, but immediately after that I got segfaults, and after reboot I get SMP errors: SMP : failed to stop secondary CPUs after running rpi-benchmark Anyone familiar with this??? – Adriaan Dec 23 '20 at 12:35

UPDATE 23 Dec 2020: resizing the rootfs to 20 GB speeds up the Pi a lot, yet mounting the other 100 GB under /data slows down the system dramatically.

UPDATE May 2021: I forgot to update this topic, but I ended up investing € 8 or so in 2 new fast MicroSD cards of 16 & 32 GB. All works stable and fast now.
