Network performance =================== The SoapyRemote server and client will use large socket buffer sizes if possible to improve performance and prevent data loss. These are larger than the default limits configured in the Linux kernel so you need to raise the limits to make full use of them. You can do this with: sudo sysctl -w net.core.rmem_max=104857600 sudo sysctl -w net.core.wmem_max=104857600 Alternatively you can create a file /etc/sysctl.d/soapyremote.conf (it is important that it ends in .conf) with the following contents: net.core.rmem_max=104857600 net.core.wmem_max=104857600 This will configure the limits automatically on every boot.
