[軟體] Lion 效能變差的可能原因
http://tinyurl.com/75wn5zw
剛剛看到這篇文章，作者推測 Lion 在 Virtual memory 管理可能有問題
導致系統做了很多不必要的 swap
他建議把 dynamic pager 關掉試試看
(P.S. 這等於關掉 swap，記憶體不夠多的人還是別這樣做吧)
關閉： Terminal 執行 (連成一行)
sudo launchctl unload -w
/System/Library/LaunchDaemons/com.apple.dynamic_pager.plist
輸入密碼，好了以後重開機就生效了
這是回復的指令：
sudo launchctl load -wF
/System/Library/LaunchDaemons/com.apple.dynamic_pager.plist
