I would definitely make sure you look at what Google is saying https://developers.google.com/analytics/devguides/collection/gajs/methods/gaJSApiBasicConfiguration#gat.GA_Tracker._setSiteSpeedSampleRate
your Google analytics code is the newest version "asynchronous tracking code" it does make a difference in speed. If you want to track your websites loading speed from certain areas or get a general idea of what you can do to speed it up I strongly recommend http://tools.pingdom.com/fpt/ or http://www.uptrends.com/aspx/free-html-site-page-load-check-tool.aspx both will allow you to check the sites load time from different areas in the United States and the world. If you want to have your site load faster than it does now and you're using Word press I would recommend a different host somebody like WPengine.com or http://page.ly/ if you are using any other form of website you can use a content delivery network somebody like http://www.akamai.com/ does a great job I also use http://www.limelight.com/website-application-acceleration/ for a more complete look at your website load speed and analytics I would recommend Adobe's Omniture http://www.omniture.com/en/ they are more expensive obviously then the free suite from Google however I believe you will see that you do get what you pay for. I also want to bring up Kiss metrics analytics they are only $30 a month and will allow you to track the speed of particular individuals here is a bit of information on the subject from their blog http://blog.kissmetrics.com/speed-is-a-killer/ as well as their main page you can sign up for a free month trial https://www.kissmetrics.com/new_feature
Here is Googles advice on what to do
_setSiteSpeedSampleRate()
_setSiteSpeedSampleRate(sampleRate)
Defines a new sample set size for Site Speed data collection. By default, a fixed 1% sampling of your site visitors make up the data pool from which the Site Speed metrics are derived. If you have a relatively small number of daily visitors to your site, such as 100,000 or fewer, you might want to adjust the sampling to a larger rate. This will provide increased granularity for page load time and other Site Speed metrics. (See Site Speed in the Help Center for details about the Site Speed reports.)
The _setSiteSpeedSampleRate()
method must be called prior to _trackPageview()
in order to be effective.
Analytics restricts Site Speed collection hits for a single property to the greater of 1% of visitors or 10K hits per day in order to ensure an equitable distribution of system resources for this feature.
Note: We strongly encourage sites with greater than 1 million hits per day to keep their sample selection set to the default 1% rate. Adjusting the sample size to a larger number will not increase your sample size.
Async Snippet (recommended)
_gaq.push(['_setSiteSpeedSampleRate', 5]); _gaq.push(['_trackPageview']);
<a class="exw-control exw-expanded">▾</a>
Traditional (ga.js) Snippet
pageTracker._setSiteSpeedSampleRate(5); pageTracker._trackPageview();
parameters
_Number_ sampleRate
Value between 0 - 100 to define the percentage of visitors to your site that will be measured for Site Speed purposes. For example, a value of 5
sets the Site Speed collection sample to 5%.
I hope I was of help to you and wish you luck with this.
