Centminmod.com Geo Location VPS Cluster Page Speed Analysis

A large part of the effort in deploying the new CentminMod.com web site design was hosting it on a Geo location based VPS cluster running Centmin Mod 1.2.3-eva2000.08 stable on all 15 VPS servers located around the world. The OpenVZ, KVM and Xen based VPS servers are located in Seattle, Los Angeles, Dallas, New Jersey, New York, London, Singapore and Sydney and currently backed by Amazon AWS Route53 latency based DNS routing.

As such average page load speed and perceived page load speed (visual rendering) should be faster if visitors are close to the geographical location of where my VPS servers and Amazon region's datacenters are.

Google Analytics Page Speed Analysis

To check if this is the case, I am going to do long term analysis of my Google Analytics custom dashboard statistics for page speed metric - particularly average document interactive time (closest approximation to visual page render time) and average page load time (includes 3rd party advertisements, GA and other 3rd party tracking codes of which I have no control over their relative speed to the visitor's location). These are real numbers that are determined by the visitor's actual internet connection speed in their regions and will highlight the fact that not everyone in the world has fast internet connections.

Note

These custom Google Analytics Page Speed Dashboards are also available for Centmin Mod Premium Members

July Analysis

I switched DNS over from DNSMadeEasy to Amazon AWS Route53 around July 28th, so it probably took July 29th-30th to propagate fully. So the first set of screenshot stats will serve as a baseline for ongoing analysis comparisons

This is for July 1st to July 30th, 2015 (this month) which shows a general downward trend (reduction) in terms page load and document interactive time - good sign



Break down the numbers by geography.



Statistics break down from my top visitor or most interested in visitor locations. A real mix, some did better some did worse on July 28th to 30th change over. Will see how this pans out over time



Mobile and Tablet page speed statistics

Top Region Analysis

The following are not Google Analystics Dashboards but just shortcuts to custom drill down views I setup, so can not be shared with Premium Members. They break down

• Avg. Document Interactive Time - the metric I am most concerned with as it closely relates to perceived visual page render time as opposed to Avg. Page Load Time which has factors outside my control like 3rd party code/js and ads.
• Avg. Server Response Time

July 26th, 2015 before DNS switch to new Geo VPS cluster

---

July 30th, 2015 today after DNS switch over. As you can see the result is mixed for Avg. Document Interactive Time but notice drastic improvement in Avg. Server Response Times - almost halved or a 1/3rd of previous times in most cases !

Still globally Avg Document Interactive Time and Avg Server Response Time respectively dropped from 2.52s to 1.83s and 0.57s to 0.23s. That's an improvement of 27.4% and 59.6% respectively



If I move it back one day to July 25th, 2015 and switch to tracking the slower top visiting countries like China, Philippines, India, Indonesia and Thailand, the numbers do show greater improvement.

Constellix Sonar Results

Looking at my Constellix Sonar results look good except for DNSMadeEasy/Constellix Sonar's Sydney location - always 600+ ms high pings for whatever reason.





Ah seems all Sydney Constellix ping checks are hitting my Singapore VPS server nodes and not my Sydney one. Looks like my Dediserve Sydney server's IP is broadcasting itself with geolocation of Indonesia and not Sydney
