PRM — Plugin Resource Meter

Always-on addon CPU & memory monitor.

(Latency · FPS · top usage rankings · history charts)

A lightweight WoW add-on that shows addon CPU and memory stats in a persistent, draggable panel — the same kind of info you get from hovering the question mark in the ESC menu, but always visible on screen.

中文简介：PRM — Plugin Resource Meter 是轻量性能监控工具，把 ESC 菜单悬停问号才能看到的统计信息，做成常驻浮动面板，随时查看，不用反复打开菜单。/prm 或小地图按钮开关监控窗。

Rename notice: Formerly Mtjcpu. Install PRM, then disable or delete the Mtjcpu folder and /reload. Old settings (MtjcpuDB) are not migrated. Leaving both enabled shows two monitors.

改名公告：原 Mtjcpu 已更名为 PRM（Plugin Resource Meter）。请安装 PRM 后禁用或删除 Mtjcpu 文件夹并重载。旧设置（MtjcpuDB）不会自动迁移。两边同时开启会出现两套监控窗。

What it shows

• Network latency (home & world)
• Current FPS
• Overall addon average & peak CPU usage
• Top addons by CPU usage (0–10, configurable)
• Total addon memory & top addons by memory
• Optional family memory total for split packs (parent + child folders)
• Per-addon CPU / memory history chart (optional recording)

Controls

• Minimap button: left-click toggles the monitor; drag to reposition
• /prm — show / hide the monitor
• If the minimap button is missing, /prm minimap shows it again
• Draggable panel; bottom-right handle resizes width; position & width saved
• Gear menu for settings; hover the help icon for usage tips
• Left-click a row: history chart · Right-click: pin / unpin · Shift+Left/Right: reorder pins

Refresh & notes

• CPU and memory refresh intervals are separate: 0–5 sec; 0 = off for that timer (last values kept; opening the window or changing settings still refresh once)
• Memory refresh triggers Blizzard’s full addon memory recount — prefer 3–5 sec if you want fewer spikes from this addon itself
• Numbers use the same kind of recent-average metrics as the ESC question-mark tooltip; sampling on an interval can differ slightly from a hover at the same moment

Notes

• No dependencies. Single-file add-on.
