I finally figured out why. I noticed some entries showing up in the Nginx virtual host error log: <code>an upstream response is buffered to a temporary file \/var\/lib\/nginx\/fastcgi\/3\/07\/0000000073 while reading upstream<\/code>. The responses from PHP were being buffered to disk (in this case, an SD card which is the boot device). I googled and found the <a href=\"http:\/\/nginx.org\/en\/docs\/http\/ngx_http_fastcgi_module.html#fastcgi_max_temp_file_size\" title=\"Nginx fastcgi_max_temp_file_size\" target=\"_blank\">option<\/a> I needed to set. Once that was set to <code>0<\/code> and Nginx was restarted, I immediately noticed an improvement in the response time.<\/p>\n<p>Before finding this, I&#8217;d tried setting various things in W3 Total Cache plugin for WordPress that didn&#8217;t make much of difference. Now some of these caching options produce a noticeable boost in performance in addition to the bump from avoiding disk buffering. Needless to say, I&#8217;m much happier with the performance.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Raspberry Pi has a 32-bit ARM CPU running at 700MHz by default, although you can usually overclock them somewhat and still enjoy stable behavior.
