Over the past several weeks we have been using this forum and webpagetest.org to help speed up our website. I have found answer to most questions I had in here, so not needed to post until now.
Our website is driven by Joomla/Virtuemart. We use Incapsula as CDN.
We have a dedicated server.
PHP Version 5.3.28
Apache Server: 2.2.23 (Unix)
Apache Cpanel: v3.18.0 rev9999
OS: Linux CENTOS 6.6 x86_64 standard
Processors: 8 x Intel Xeon E31230 @3.20GHz (Cache 8192kb)
RAM: 4096MB DDR3
Our initial results were very poor with Fs across the board and 12s load time (http://www.webpagetest.org/result/150118_YB_GQJ/)
After this we installed Incapsula etc. We also have since changed the website skin, and set about improve our results.
Here is the latest results: http://www.webpagetest.org/result/150527_BE_6b3f9517c3c2595632d510a7c957aaea/
Do we proceed as we are doing just now in fixing the render-blocking items as we can, or is there something else we should be considering ?
We made a test page to strip it down to see if we could reduce TTFB (first byte reduced from 1.36s to 0.277s)
This test page is a “view source” of the website homepage, including all the Joomla code that is genereted on the server.
