Load Time Notes
Column 1 gives the website name. This data was taken on
September 6, 2011.
All Alexa data is taken from
Column 2 is the load time in seconds given by Alexa
Column 3 shows Alexa comments - For fast sites, Alexa
says "xx% of sites are Slower -
For slow sites, Alexa says
"xx% of sites are Faster.
Alexa chooses not to be
Alexa actual data is
highlighted in yellow in Column 3.
Column 4 shows the "speed class" which corresponds to the
Alexa load time given.
Lines are also drawn comparing
my sites' data from Alexa, with my sites' data from
This illustrates the
considerable discrepancy between Alexa and Google.
Column 5 is the load time in seconds given by Google
MY actual data is
highlighted in yellow in Columns 5, 6 and 7 - other
numbers are extrapolated.
Column 6 and 7 show "faster than" percentages for each
Google load time.
Column 8 show the "speed class" which corresponds to the
Google load time given.
Column 9 shows the price paid in load time for using
approximately 1/2 second to load time.
It is fascinating that Google Search advises to REMOVE
To please the "speed folks" at Google, one must DROP all
To please EVERYONE ELSE at Google, one should INCLUDE all
Why the big discrepancy between Alexa and Google? Some
Alexa does not.
The difference is relatively HUGE - about 1
BOTH Alexa and Google place the dividing line between fast
and slow at about 1.6 to 1.7 seconds.
Alexa also provides 3 other speed classifications - average,
very fast, and very slow.
Site 1 (slow - 2.6 seconds) has Google Analytics, Google
AdSense and Google +1 buttons.
Site 2 (fast - 1.2 seconds) does NOT have Google Analytics,
Google AdSense or Google +1 buttons.
Both are on the same server, at the same host.
My conclusions -
1. Every Java code occurrence
adds about 1/2 second to load time.
2. The Google +1 buttons MUST
be removed, to speed up your pages.
3. Google Analytics SHOULD be
removed, to speed up your pages.
4. Google AdSense will remain
(unless speed is your absolute objective).
It would be fantastic if the Google "speed-folks" would talk
to their peers, and come up with guidelines.
Since anything slower than 1.6 seconds is officially "SLOW"
(WMT), will we get penalized beyond 1.6 seconds?
Or would Google rather just keep us guessing? It is hard to
comply with nebulous hints which specify nothing.
You want fast? Please define fast. Google WMT defines fast
as "faster than 1.5 seconds".
If that is taken literally, it DEMANDS the removal of ALL
According to Google WMT, only 20% of sites qualify as
Google may wish to re-think their various pronouncements,
and come up with an INTEGRATED, company-wide policy.
Something like, "1.5 seconds, UNLESS you are using
AdSense". "And/or Analytics". "And/or +1".
ALL we want to know is, "When does ANY type of penalty
kick-in? ONLY THEN, can we address the issue.
Otherwise, webmasters are going to be DROPPING GOOGLE
functions, perhaps needlessly.
