If I change settings like this for example:
# sysctl -w net.core.rmem_default=500000 # sysctl -w net.ipv4.tcp_rmem='4000 90000 10000000'
- Is it safe to do this in a heavy duty live production machine (CentOS 7)? Are there any known risks?
- Does this change apply to previously established sockets that are currently streaming data on the system?
- If not, does this change require the process or the shell to be restarted to take effect?
