COW page
鬼車に対して、パッチ付きのメールが来た。
> size .libs/libonig.so text data bss dec hex filename 273707 5284 680 279671 44477 .libs/libonig.so > Because the data section is larger than 4096 bytes, it means that every process that is linked to liboniguruma.so needs at least two COW pages for global writable data. I'm trying to reduce the size of the data section to less than 4096 bytes, so oniguruma only needs one COW page.
COW pageを一個に縮小できると、何がどの程度良くなるのか見当がつかないのだが、どうしたものだろう。
