內容簡介
當有評論的文章和頁面中,創建頁面中最耗時的部分就是將表情符號轉換為圖像的翻譯!
這在WordPress 2.8-bleeding-edge中已經得到修復,但如果你沒有使用,(在生產中你可能不應該,但!)這個外掛程序仍然可以加速處理速度。
它替換了smilies_init為一個新的,構造了一個更有效的常規表達式,顯著增加了處理表情符號更快的效率。
注意:它使用"e"修飾符來替換preg_replace來避免修補任何核心文件。但不是所有主機都允許這樣做。
性能
一個在WordPress 2.7中的25個評論的頁面平均創建速度快了28%!

原文外掛簡介
On posts and pages with comments the most timeconsuming part in page creation is translating the smilies to images!
This has now been fixed in WordPress 2.8-bleeding-edge, but if you are not using that (and in production you probably shouldn’t, yet!), this plugin gives you the speedup anyway.
It replace smilies_init with a new one that constructs a more efficient regular expression, resulting in 10 ggr faster handling of smilies replacement.
Note: it uses the ‘e’ modifier to preg_replace to avoid patching any core files. Not all hosts allow this.
Performance
A page with 25 comments on an otherwise empty WordPress 2.7 got created on average 28% faster!
