apache benchでパーフォーマンス測定してみる。
$ ab -n 10000 -c 300 https://ras.viasv.com/wordpress/ This is ApacheBench, Version 2.3 <$Revision: 1826891 $> Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Licensed to The Apache Software Foundation, http://www.apache.org/ Benchmarking ras.viasv.com (be patient) socket: Too many open files (24)

$ ab -n 10000 -c 30 https://ras.viasv.com/wordpress/
