I set dbcache=4000 in my bitcoin.conf file, but where can one confirm if this took affect or not in the gui? I'm on ubuntu 18.

  • Have you tried simply checking memory usage during sync?

  • you mean with the "free -h" command? Commented Oct 19, 2018 at 15:42
  • yes. dbcache sets how much ram is used during the validation process, if I'm not mistaken

  • But where can I see it in the Bitcoin client where it shows that its really set? Using free -h doesn't really say fore sure its that application using it or not. Commented Oct 19, 2018 at 16:30
  • If it's in the conf file, instead of a command line flag, then I don't think there is a way to know which settings it's using other than verifying that your conf file is working by changing other settings and seeing if they take effect.

When you run bitcoind you can see it popup on the loading screen. If it shows up here, it will be the same when you run the bitcoin-qt gui wallet too.
