TickWait

# TickWait ## How long does your server wait for a CPU? When the machine under your server is busy, the main thread queues for a core and every tick starts late — and nothing in the console shows it. TickWait reads the kernel's own counters for the main thread once a second and tells you how long it waited and why: - **at your plan's CPU limit** — the server's cgroup was throttled, - **behind your server's own threads** — garbage collection, chunk workers, plugins, - **other work on the same cores** — other servers, the host. On current Paper and its forks it also splits every tick into CPU work, waiting for a CPU, and the rest. ## Commands `/tickwait status` · `/tickwait report` · `/tickwait export` · `/tickwait share` · `/tickwait unshare ` — all need `tickwait.admin` (operators by default). ## What leaves your server Nothing, unless you run `/tickwait share` and confirm. Then it uploads per-hour CPU, tick and player-count sums, the CPU model, CPU count and limit, cgroup version, OS, kernel, Java and server versions, and any host/plan labels you set to truetick.gg, and prints a public link (not indexed by search engines). Not the server's address, player names, the world or chat. `/tickwait export` shows the exact upload first; `/tickwait unshare ` deletes it. ## Requirements Linux, Paper, Spigot, Purpur or another Paper fork, Java 8 or newer. Run on: Paper 1.21.11 and Purpur 1.21.11 (per-second and per-tick split), Spigot 1.21.11 and Paper 1.8.8 (per-second split). Folia isn't supported yet.

It measures every host the same way, ours included. TickWait was written with Claude, Anthropic's AI, and tested on TrueTick's servers.
