I started playing with bitcoind 0.18.1 on a RPI4 and i can see that even when fully synced it is still using 100% cpu so one full core.
Is this normal / expected ?
Looking at the threads is the
bitcoin-msghand (ler?) thread that is doing the work
5946 999 20 0 557016 410080 3392 R 98.8 10.2 226:58.92 bitcoin-msghand
could it be that my
dbcache=100 is causing it to do much IO while relaying data to other peers ?
To be fair i don't see much IO at all
