emacs lisp defuns to change the case (camelCase <-> snake_case) of the word under cursor, or an entire region if selected. NOTE: the snake-case defuns do not work, they just camelCase. Ooops.
;; Grateful thanks are given to Brian Marick (@marick) for helping me
;; write these. I got the original idea while reading through
;; http://xahlee.org/emacs/elisp_idioms.html, but couldn't work out
;; the elisp regexes. Brian Marick (@marick) stepped in and helped. He
;; took my tortured and broken camelcase-region and turned it into
;; something that actually worked. I then created
;; camelcase-word-or-region. I then wrote the snakecase versions but I
;; see now that all I did was copy the camelcase defuns over and,
;; meaning to go back and finish them Real Soon Now, forgot all about
;; them. I've had a quick look (2011-02-27) but elisp regexes are

コマンドによる「負荷」の原因切り分け

コマンドによる「負荷」の原因切り分け

この文章では、Linuxコマンド、sar, top, psを使って、一般的に負荷といわれるものの原因を切り分けることを目的とする。

そもそも負荷とは

「複数のタスクによるサーバリソースの奪い合いの結果に生じる待ち時間」を一言で表した言葉。OSのチューニングとは負荷の原因を知り、それを取り除くことにほかならない。

ボトルネックの見極め作業の大まかな流れ

  • ロードアベレージ(処理を実行したくても、実行できなくて待たされているプロセス(CPUの実行権限が与えられるのを待っている、またはディスクI/Oが完了するのを待っている)の数)を見る
