 Example: Assuming 1Gbps link with 256ms RTT, it's a 32MiB maximum window size requiring 64MiB maximum buffer size. Add `net.ipv4.tcp_rmem = 4096 131072 67108864` to client-side sysctl.conf, `net.ipv4.tcp_wmem = 4096 131072 67108864` to server-side sysctl.conf.
 
-BBR should be able to reduce the buffer size to reduce bufferbloat.
+BBR should be able to auto-tune the buffer size to reduce bufferbloat.
