apache でコンパイル時に、取り込んでます。

コンパイル時のオプション
./configure \
--prefix=/usr/local/apache2.2 \
--with-mpm=worker \
--enable-so \
--enable-shared \
--enable-deflate=shared \
--enable-cache \
--enable-disk-cache \
--enable-mem-cache \
--disable-info \
--disable-status \
--disable-include \
--disable-rewrite \
--disable-imap \
--disable-ipv6

１回キャッシュするとかなり速いですね。
lighttpd+FastCGIも考えているが、結局のところ、外から繋いでどれだけ速いかだし。ルータも交換するぞ( ・ω・)∩

とりあえず設定です。httpd.confに追加。
< IfModule mod_cache.c >
< IfModule mod_mem_cache.c >
CacheEnable mem /
## CacheDisable /home/hoge ←キャッシュしたくないのはこれで追加。
MCacheSize 256000
## MCacheMaxObjectCount 3000　キャッシュの数の指定だけど今回は無し。
MCacheMinObjectSize 1
MCacheMaxObjectSize 128000
MCacheMaxStreamingBuffer 128000
< /IfModule >
< /IfModule >

abでベンチします。
