Challenge

To maintain high quality customers service online the owners made a decision to switch store performance speed to the next gear.

Speed up mobile upload

Increase desktop load speed

Analytics and Solution

To locate performance issues, we performed a complex analysis of the store, including both server and CS-Cart speed optimization analysis.

Eliminate code blockage

Speed up server response

Implementing the Project

Eliminate render-blocking JavaScript
and CSS in above-the-fold content

We found out that the client modified the code to block automatic script displacement down the page. This modification decreased page loading time.

We brought the code back to original view.

Development of additional functionality and
integration with third-party services

Overwhelming amount of sessions in Redis

Redis is an in-memory data structure store, used as a database, cache and message broker. Every website visitor creates a session which is being stored in Redis around a month. The store periodically extracts all sessions from Redis and replaces the old ones with new. There were 75 355 sessions in WatchBand storage at the moment we started the project. Due to sessions amount extracting was very slow and caused around two seconds response delay.

Commented out code in “clear” function

This function serves to clear Redis cache. It triggers every time the database changes. It happens very often (log change, order placed, adding to cart). After clearing up the cache builds up back. Commented out code on WatchBands was slowing down this process.

We reviewed the code and fixed it.

«Minify HTML» CS-Cart Add-on installed

This is a free add-on that makes HTML more compact by removing unnecessary white spaces, line breaks, tabs and other extra objects. It makes websites load faster, reduces mobile transfer costs and optimizes storage on embedded systems.

Images optimization

To speed up images upload we re-saved them with more compact .jpeg compression. Smaller image sizes means faster page loads, faster backups, less bandwidth usage and happy customers.
