Já está nos kernels mais modernos, e compilo ele como default em meus novos
servidores.

CONFIG_TCP_CONG_BBR:

│
│
  │ BBR (Bottleneck Bandwidth and RTT) TCP congestion control aims
to
│
  │ maximize network utilization and minimize queues. It builds an
explicit
│
  │ model of the the bottleneck delivery rate and path
round-trip
│
  │ propagation delay. It tolerates packet loss and delay unrelated
to
│
  │ congestion. It can operate over LAN, WAN, cellular, wifi, or
cable
│
  │ modem links. It can coexist with flows that use loss-based
congestion
│
  │ control, and can operate with shallow buffers, deep
buffers,
│
  │ bufferbloat, policers, or AQM schemes that do not provide a
delay
│
  │ signal. It requires the fq ("Fair Queue") pacing packet
scheduler.
