Just make sure that the correct architecture is set, too. `-march=native` usually works quite well.
## Disable Nulticast Local Peer Detection
For better local peer detection, the edges try to detect local peers by sending REGISTER
packets to a certain multicast address. Also, edges listen to this address to eventually
fetch such packets.
If these packets disturb network's peace or even get forwarded by (other) edges through the
n2n network, this behavior can be disabled, just add
`-DSKIP_MULTICAST_PEERS_DISCOVERY`
to your `CFLAGS` when configuring, e.g.
`./configure --with-zstd CFLAGS="-O3 -march=native -DSKIP_MULTICAST_PEERS_DISCOVERY"`
