Nginx Wordpress php-fpm fastcgi_cache + Google Nginx PageSpeed

Hi folks, wondering if anyone here has tested Nginx php-fpm fastcgi_cache with Google ngx_pagespeed module ?

 

I am testing Centmin Mod v1.2.3 beta install of Nginx 1.4.1 + PHP 5.3.25 (php-fpm) with ngx_pagespeed 1.5.27.3 beta and wanting to see how it would fair with a fresh Wordpress 3.5.1 install at localhost/wp. 

 

Results:

 

  1. I successfully tried setting up fastcgi_cache for php for wordpress http://centminmod.com/nginx_configure_wordpress.html#fastcgicache
  2. Enabling ngx_pagespeed enabled top of this, works fine for ngx_pagespeed itself http://centminmod.com/nginx_configure_wordpress.html#pagespeed
  3. But, with ngx_pagespeed enabled, it drops Siege benchmark performance back to non-fastcgi_cache levels as if ngx_pagespeed rendered fastcgi_cache useless ? Curious if anyone has experienced the same ?
 

Below is nginx restart output along with curl header for localhost/wp and siegebenchmark results for wordpress fastcgi_cache php-fpm

 

  • With ngx_pagespeed off, Siege benchmark = 2,403 requests/s
  • With ngx_pagespeed enabled + memcached, Siege benchmark only manages 266 requests/s
  • With ngx_pagespeed enabled and memcached disabled, Siege benchmark results in 225 requests/s

<Edit: After actually reading how nginx handles upstreams, this can't possibly be the case (fcgi caching pagespeed). Let this be a lesson to anyone who would post w/o sleeping.>

Hello, i see "ngx_pagespeed" is included in Your Centmin Mod LEMP stack if im correct. Does it mean that if pagespeed is enabled, requests/second is lower than when module is disabled ?

with ngx_pagespeed enabled, it drops Siege benchmark performance back to non-fastcgi_cache levels as if ngx_pagespeed rendered fastcgi_cache useless ?
  • With ngx_pagespeed off, Siege benchmark = 2,403 requests/s
  • With ngx_pagespeed enabled + memcached, Siege benchmark only manages 266 requests/s
  • With ngx_pagespeed enabled and memcached disabled, Siege benchmark results in 225 requests/s
Thank you
