Overview ¶

Package tuning applies host-level network optimizations recommended for an Xray server — currently enabling the TCP BBR congestion-control algorithm, which noticeably improves throughput on lossy/long-haul links.

See https://xtls.github.io/en/document/level-0/ch07-xray-server.html (7.7).

Functions ¶

func Active ¶ added in v0.13.0

func Active() bool

Active reports whether BBR is the congestion-control algorithm in force right now. It re-reads the kernel rather than trusting what EnsureBBR returned at boot, so the health report reflects reality even if something changed the sysctl since.

Types ¶

type BBRState ¶

type BBRState int

BBRState is the outcome of EnsureBBR, for logging.

const (
	BBRAlready   BBRState = iota // already active, nothing to do
	BBREnabled                   // we just switched it on
	BBRUnchanged                 // couldn't enable (kernel lacks BBR, not root, …)
)

func EnsureBBR ¶

func EnsureBBR() (BBRState, error)

EnsureBBR enables BBR congestion control if it isn't already active. It persists the setting via a sysctl drop-in (so it survives reboots) AND applies it at runtime, so no reboot is needed. Best-effort and idempotent: it returns the resulting state plus any error for the caller to log, and never fails the boot. Requires root (the panel runs as root under systemd); on a non-Linux/non-root host the /proc and /etc writes simply fail and it reports BBRUnchanged.
