On my machine with 6 GB RAM the bitcoin-qt -min command consumes ~17% of my whole RAM which is too much in my opinion. Also, there are 21 child processes.
How can I limit the number of child processes and the overall memory usage? I am on Ubuntu 14.10 here and the Qt version is 4.8.6.
You can lower the number of threads e.g. for -par or -rpcthreads and limit or disable inbound connections for example.
In the .conf file? Or where? An example would be good. Thanks!
See here for some tips on reducing bitcoind memory usage: https://gist.github.com/laanwj/efe29c7661ce9b6620a7
@laanwj Thanks but I am referring to bitcoind-qt here, not to bitcoind.
And it is not clear to me where to add these parameters exactly?
@binarykitchen See https://en.bitcoin.it/wiki/Running_Bitcoin.
You can either put the command line options in a bitcoin.conf file and put that in your data directory; or pass them to bitcoin-qt on the command line. i.e
./bitcoin-qt -par=2 -rpcthreads=3 -dbcache=150
Ah, this worked. Thanks!
