Description
Increases size of UDP socket buffers for sui, primary, and worker Anemo networks. This improves performance under high load.
Test Plan
Manual benchmarks & testing on private-testnet.

Type of Change (Check all that apply)
Release notes
Increases size of UDP socket buffers for sui, primary, and worker Anemo networks. This improves performance under high load.
NOTE: the buffer sizes requested after this change are larger than the default maximum buffer allowed by many operating systems. If the sui node binary logs errors about failure to set UDP socket buffer size, you may need to increase the maximum allowed by your OS.
Some examples:
sudo sysctl -w net.core.rmem_max=104857600; sudo sysctl -w net.core.wmem_max=104857600sudo sysctl -w kern.ipc.maxsockbuf=104857600
