本陣を触る。
Mac clients 200 / thred per child 50 = 4 つのプロセスが出来るはず?
最初から4つ作っておいてみる。
<IfModule mpm_worker_module>
StartServers 4
MaxClients 200
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 50
MaxRequestsPerChild 0
</IfModule>
確かにそうなってる？

デフォルトと同じく6つプロセスが立つようにしてみる
<IfModule mpm_worker_module>
StartServers 4
MaxClients 300
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 50
MaxRequestsPerChild 0
</IfModule>
プロセスは最初4→2、で高負荷になると6に戻った。

仮想メモリ的に132MBぐらい？なので10プロセスで1.3Gぐらいメモリを食うのか。
あんまりapacheにメモリは裂けないので、これぐらいで良しとする。
