Net autotuner

[geobarrod]

If you wish to dynamically adjust the TCP stack, the congestion control algorithm, buffers, and queues based on real-time network metrics such as latency, packet loss, jitter, throughput, kernel drops, and out-of-order segments, this system is designed to optimize FreeBSD networking performance under diverse and changing conditions.

Thanks, but i don't need automatic. I need output :
- Put this is sysctl.conf
- Put this in rc.conf
- Put this in resolv.conf
- Etc ...
