It is possible to limit the network usage of geth/parity while updating my node?
I want to be able to update (slowly, this doesn't matter), to reduce the strain on my network. Does anyone know a way to do this within geth or parity?
Use 'trickle' - https://wiki.archlinux.org/index.php/trickle
In Ubuntu (for example):
sudo apt-get install trickle
Then to run the geth client with upload limited to 50kb/second, simply use trickle (which executes geth for you):
trickle -u 50 ./geth
