We repeat many peers each time we call SetPeers. Instead of constructing strings for them from scratch every time, keep strings alive across iterations. name old time/op new time/op delta SetPeers-8 3.58µs ± 1% 2.41µs ± 1% -32.60% (p=0.000 n=9+10) name old alloc/op new alloc/op delta SetPeers-8 2.53kB ± 0% 1.30kB ± 0% -48.73% (p=0.000 n=10+10) name old allocs/op new allocs/op delta SetPeers-8 99.0 ± 0% 16.0 ± 0% -83.84% (p=0.000 n=10+10) We could reduce alloc/op 12% and allocs/op 23% if strs had type map[string]strCache instead of map[string]*strCache, but that wipes out the execution time impact. Given that re-use is the most common scenario, let's optimize for it. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com> |

Tailscale
Private WireGuard® networks made easy
Overview
This repository contains all the open source Tailscale client code and
the tailscaled daemon and tailscale CLI tool. The tailscaled
daemon runs primarily on Linux; it also works to varying degrees on
FreeBSD, OpenBSD, Darwin, and Windows.
The Android app is at https://github.com/tailscale/tailscale-android
Using
We serve packages for a variety of distros at https://pkgs.tailscale.com .
Other clients
The macOS, iOS, and Windows clients use the code in this repository but additionally include small GUI wrappers that are not open source.
Building
go install tailscale.com/cmd/tailscale{,d}
If you're packaging Tailscale for distribution, use build_dist.sh
instead, to burn commit IDs and version info into the binaries:
./build_dist.sh tailscale.com/cmd/tailscale
./build_dist.sh tailscale.com/cmd/tailscaled
If your distro has conventions that preclude the use of
build_dist.sh, please do the equivalent of what it does in your
distro's way, so that bug reports contain useful version information.
We only guarantee to support the latest Go release and any Go beta or release candidate builds (currently Go 1.16) in module mode. It might work in earlier Go versions or in GOPATH mode, but we're making no effort to keep those working.
Bugs
Please file any issues about this code or the hosted service on the issue tracker.
Contributing
PRs welcome! But please file bugs. Commit messages should reference bugs.
We require Developer Certificate of
Origin
Signed-off-by lines in commits.
