How to tell bitcoind to use more memory and CPU I just updated my node to 0.12 and its going through its long verification process but I noticed that its not using very much memory/cpu

pi         602 10.5 19.4 352220 184312 ?       Ssl  21:57   1:28 /usr/local/bin/bitcoind -datadir=/home/pi/bitcoinData/.bitcoin -daemon


How can I configure it to optimise all available memory and cpu? I recall a option to bump up the cache from a default of 50 or 100mb but cannot find the option.

I have a 1GB PI 2. Any recommendations on maximum memory to use? I was thinking 900mb if possible.

Thank you for your tips, and any optimizations to make this run best would be great!
It will by default use all CPU cores available.

However, if the database cache is too small, your node will spend its time fetching and writing database entries from/to disk, rather than verification

You can set the size of the database cache using a bitcoin.conf setting dbcache=N, where N is the number of megabytes of RAM.
