CPU usage lower than i expected and there's 1GB+ of free swapfile. HDD usage and response time is also normal (assuming HDD is /sda).
Can you run both ps aux | sort -nrk 3,3 and iostat -d -x when you execute command on bitcoin-cli?

Topic: Slow respond from raspberry pi full node (Read 225 times)
Thank you for all suggestions. I have HDD drive. Bellow are the results from commnads.
Also I realised that I had very quick response from commands bellow but I was doing this in administrator user. But bitcoin-cli is running under another user. So if I run getblockchaininfo it still needs around 10 seconds for response.

Sounds like memory issues. How much memory has it in use on standby? How big is your swap file ? Maybe increase the swapfile will do the trick.
Which model do you exactly have? @Zand_ has been running full Bitcoin nodes on two different Raspberry Pies 3 B+ without any problems. However, we ran into issues with LND. Sometimes, it takes a few minutes for an off-chain transaction to go through. The problem seems to be related with too low processing power. The reason might be the same in your case if you own a Raspberry Pi one or two.
What external drive you have to run a full node? Do you run the rasp Pi with a fan?
What I heard from the other they are using SSD drive because it is much faster than HDD also if you are running a Raspberry Pi without a fan it might throttle the CPU speed.

Hi. I'm running full node on R. Pi. I control it over Putty ssh conection. When I start comand like bitcoin-cli geblockchaininfo (or getpeerinfo) result comes after more then 20 seconds, sometimes over a minute. Does anybody have any idea or suggestion how to solve this issue?
