把 googleapis 替换成 useso 即可:
sed -i s/googleapis/useso/g `grep -rl googleapis ./wordpress`
另外在后台关闭Gravatar头像显示(设置-讨论-头像显示),免得拖慢页面加载速度.
要成倍提升WordPress速度,可以考虑使用PHP7,参考:

查看哪些文件在哪些行包含了googleapis串:
grep -rn googleapis ./wordpress-4.2

可以考虑使用下载到本地的JS文件并且禁用在线字体:
引入字体的地方可以注释掉,变量则置为空.
JS文件则替换为本地文件:
cd wordpress && mkdir ajax
wget \
ajax.useso.com/ajax/libs/prototype/1.7.1.0/prototype.js \
ajax.useso.com/ajax/libs/scriptaculous/1.9.0/scriptaculous.js \
ajax.useso.com/ajax/libs/scriptaculous/1.9.0/builder.js \
ajax.useso.com/ajax/libs/scriptaculous/1.9.0/dragdrop.js \
ajax.useso.com/ajax/libs/scriptaculous/1.9.0/effects.js \
ajax.useso.com/ajax/libs/scriptaculous/1.9.0/slider.js \
ajax.useso.com/ajax/libs/scriptaculous/1.9.0/sound.js \
ajax.useso.com/ajax/libs/scriptaculous/1.9.0/controls.js \
ajax.useso.com/ajax/libs/jquery/1.7.2/jquery.min.js
./wp-includes/script-loader.php 里改为:
$scripts->add( 'prototype', '/ajax/prototype.js', array(), '1.7.1');
$scripts->add( 'scriptaculous-root', '/ajax/scriptaculous.js', array('prototype'), '1.9.0');
$scripts->add( 'scriptaculous-builder', '/ajax/builder.js', array('scriptaculous-root'), '1.9.0');
$scripts->add( 'scriptaculous-dragdrop', '/ajax/dragdrop.js', array('scriptaculous-builder', 'scriptaculous-effects'), '1.9.0');
$scripts->add( 'scriptaculous-effects', '/ajax/effects.js', array('scriptaculous-root'), '1.9.0');
$scripts->add( 'scriptaculous-slider', '/ajax/slider.js', array('scriptaculous-effects'), '1.9.0');
$scripts->add( 'scriptaculous-sound', '/ajax/sound.js', array( 'scriptaculous-root' ), '1.9.0' );
$scripts->add( 'scriptaculous-controls', '/ajax/controls.js', array('scriptaculous-root'), '1.9.0');
