For a WebSDR minimum latency is essential. That needs controlling buffer sizes.

In the startup scripts we have added the lines:

 

## set network socket buffer default size temporarily

sudo sysctl -w net.core.rmem_default=100000

 

## set fixed: add in /etc/sysctl.conf

#net.core.rmem_default=100000

 

We didn’t want to set it fixed to 100000, so we use the first command line.

 

Note: the FPLAY buffer size is also set to 100000 in the startup script for PCMCAT.
