https://developers.google.com/speed/pagespeed/mod I've just downloaded and installed the Debian AMD64 package of the Google Apache Pagespeed module. https://developers.google.com/speed/pagespeed/insights#url=etbe.coker.com.au... https://developers.google.com/speed/pagespeed/insights#url=etbe.coker.com.au... According to the above URLs the web performance scores for my blog were 93 for non-mobile and 88 for mobile both before and after installing mod_pagespeed. It appears that Pagespeed isn't doing any good according to Google's analysis! etbe.coker.com.au 10.0.151.178 - - [13/Oct/2012:05:22:31 +0000] "GET /wp- content/plugins/openid/f/W.openid.css,qver=519.pagespeed.cf.Bbu1gxRjUE.css HTTP/1.0" 200 2165 "http://etbe.coker.com.au/" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1" 0 etbe.coker.com.au 10.0.151.178 - - [13/Oct/2012:05:22:31 +0000] "GET /wp- content/themes/atahualpa/js/DD_roundies.js,qver=0.0.2a.pagespeed.jm.4gw5yluag0.js HTTP/1.0" 200 3679 "http://etbe.coker.com.au/" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1" 0 etbe.coker.com.au 10.0.151.178 - - [13/Oct/2012:05:22:31 +0000] "GET /wp- includes/js/jquery/jquery.js,qver=1.7.2.pagespeed.jm.XZwfunyK-6.js HTTP/1.0" 200 33587 "http://etbe.coker.com.au/" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1" 0 etbe.coker.com.au 10.0.151.178 - - [13/Oct/2012:05:22:33 +0000] "GET /wp- content/themes/atahualpa/images/xlogo.png.pagespeed.ic.ICWmaHBME5.png HTTP/1.0" 200 2267 "http://etbe.coker.com.au/" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1" 0 The above sample of web logs shows that the string "pagespeed" is appeneded to some URLs with a hash of the file contents which apparently allows much longer cache times without making it difficult to change content. So Pagespeed is obviously doing something. Is Google analysis expected to say that there is no change? Note that my speed scores are 93% and 88% so my site is was apparently quite good before mod_pagespeed was installed - maybe the analysis would report a difference on a site that didn't perform so well. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
