內容簡介
即使伺服器有其「保護」以免過載而丟出 503 錯誤，但當此情況發生時，伺服器已經可能非常負載。此外掛會檢查實際的 CPU 負載，若高於某個特定值（預設為每核心的 2 倍），便會顯示錯誤訊息。
此外掛僅採用簡單的檢查方式，絕非適當的負載平衡的替代方式。但在你的伺服器系統進行調整或大量維護、遭受較弱攻擊等情況時，此外掛仍可趁虛而入，特別是你不希望完全停用網站時。
目前僅支援 Linux 伺服器（已測試），其他 UNIX 系統應該也可以正常運行。
路徑圖：
快取偵測（如果頁面已快取，則無論負載如何仍提供快取的頁面）
支援 Windows 伺服器
測試伺服器的相容性
將設定儲存於資料庫外以加快速度

原文外掛簡介
Even though servers do have their “protection” against overload throwing a 503 error, at the time when this happen, server can be really overloaded already. This plugin checks the actual CPU load and if higher than specified (by default 2 per every core), displays an error message.
Very simple checking is used and by no means is this a replacement to proper load balancing. Can be useful though, especially when your server system is undergoing a tuning or heavy maintenance, is under weak attack, etc. and you don’t want to disable the site completely.
Currently only Linux servers are supported ( = tested), other UNIX systems should work as well.
Roadmap:
Cache detection (if page is cached, serve it regardless the load)
Support for Win servers
Test server compatibility
Storing settings outside of database for speed improvement
