imall Speed Optimization Implementation Comparison Report

cheap nfl jerseys Previously, we received many customers complaints that our imall website speed was kind of slow. In order optimize customer’s experience, we have greatly increased the speed. Here please view our comparison report.

Data of this report was generated by a third-party web analytics tools called GTmetrix Cheap Jerseys free shipping
. This tool apply two kinds of rules- pagespeed and YSlow to analyze web pages and provide optimal solutions.

On February 17th, 2016, we made incremental upgradation to imall existing configuration. The original cpu was 2 core and original memory was 2g, now the cpu is 8 core and memory is 8g.

The response speed of imall backend nginx+php5-fpm+magento has reduced from about 425.672ms to 179.821ms, which has shorten 245.851ms and increased the performance to 136%.

On February 18th, 2016, we used gtmetrix.com to monitor(pagespeed/yslow analysis) https://www.itead.cc/ and plus physical distance delay, it required 500ms to complete download homepage html.

Below is 3-day test result on GTmetrix:

On February 20th, 2016, we upgraded nginx imall service. The upgradation version is 1.9.11 and open to support HTTP/2.

Page load time decreased from 2.2 seconds to 2.08 seconds.

GTmetrix Test Report Screenshot:

In consider that apply HTTP/2 to high RTT area will increase the load time, also consider whether we need HTTP/2 after subsequent CDN migration, we temporarily do not open support to HTTP/2.

On March 2nd, 2016, resource migration CDN
GTmetrix overall test value: (Highest: Sydney 6.1s; Lowest: Canada 1.7s)

After completing the migration, we made a new round of testing, the result was: (Highest: Sydney 5.6s; Lowest: Canada 1.6s) Other places averagely reduced delay 0.77s, averagely increased speed by 17%. Asia, the Americas and Australia had the greatest improvement. 

GTmetrix Canada detailed report: compare to last report, YSLOW score has increased 7%, which is the result of CDN acceleration.

Overall, the acceleration of this round has basically reached our target. We will continue to optimize if there is any chances to delayed loading JS, reduce the image size, etc.
