An e-Commerce Business from Europe: A Real-world Performance Optimization Journey

Disclaimer: We can not expose the client's name due to the NDA terms with them

Performance Issue Reported by Client:

• Slow loading speed of site pages: A single page load takes 3 to 15 seconds in a regular scenario and 10 to 30+ seconds in extreme cases.
• Time-Out Errors: The site frequently shows time-out errors from the database while customers browse the category pages and when the site has only 60+ customers online.
• Spikes in Database Performance Graph: A lot of spikes in the Database performance graph are seen, even on a very limited number of visitors on the site.
• Suspicious Guest Customers: A huge number of guest customers gets created even on a single crawler visit.
• Slower Load speed on Mobile devices: Some pages on mobile devices take more than 20s to load.

Our Findings:

• Codebase Review: We have reviewed their code base, especially those areas where Database requests got time out.
• Complex Implementation of Business Logic: We have found that they have implemented one of the business logics in a very complex way, which led to too many requests to the Database, also in one method they were retrieving whole products in memory to do filtering on price.

• Too many DB Calls for Simple Category Page Load: We have analysed and found they make a large number of Database requests to load one simple category page.

• Lack of Cache Implementation: We have found that they did not implement proper caching techniques to reduce the number of requests to the Database.
• PageSpeed Insights Findings: We found that they have unnecessary loading of JS files and large content like images is being served from the application server. They have a dependency on 3rd party JS and CSS files etc.

Our Actions:

• Source Code Modification: We have modified a few areas in their source code to implement a few business logic in a better and simpler approach.
• Implementation of Caching: Implemented proper caching where required.
• Database Index: Include some Database Index to optimize the query performance.
• Query Optimization: Used Tempt Table to join query with product table instead of running WHERE / IN query for a list in the product table.
• Updating CrwalersOnly XML: We have updated browscap.crawlersonly.xml which includes a wide list of bot user agents.

The Outcome:

• Lighting Fast Page Load Speed: After optimization, the site's pages take less than a second in regular site visiting hours and not more than 5 seconds in extreme pick-hours.
• Time-Out Issue Resolved: All Database time-out issues related to calls to the database are resolved. The maximum time taken for a Database request to pull products is now only 1.6 seconds, by the search products method.

• Precise BOT Protection: The site now can detect most of the bots and handle them accordingly as a search engine customer instead of creating new guest customers.
• PageSpeed Insights Findings: We found that they have unnecessary loading of JS files and large content like images is being served from the application server. They have a dependency on 3rd party JS and CSS files etc.

Further Recommendation :

• We have suggested the client use CDN.
• Minimize the use of third-party scripts and plugins.

Airloom: Soaring to New Heights with Improved Performance

Performance Issue Reported by Client:

• Slow loading speed of site pages: A single page load takes 4 to 20 seconds in a regular scenario and 10 to 30+ seconds in extreme cases.
• Spam Registration and Bot Browsing: Tens of thousands of fake customers were created in the database and contributed to the slowed page-load of the website by bots.
• Spikes in Server Performance Graph: A lot of spikes in the CPU performance graph are seen, even on a very limited number of visitors to the site.
• Slower Load speed on Mobile devices: Some pages on mobile devices take more than 20s to load.

Our Findings:

• Non-Standard Implementation of Business Logic: We have found that they have implemented some of the business logic in a non-standard and incorrect way, which led to too many requests to the Database, leading to performance downgrade and taking a long time for the query execution – in the worst case which sometimes takes 5 minutes to load a particular page.
• Use of Old Version of nopCommerce The client was using nopCommerce version 4.20. The use of the outdated version of nopCommerce contributed to significant performance issues, as older versions lack essential updates, security patches, and optimizations, hindering the website's speed, functionality, and overall user experience
• Lack of Cache Implementation: We have found that they did not implement proper caching techniques to reduce the number of requests to the Database.
• Use of Non-Optimized Images: We found that unoptimized images were being used on the site. The utilization of non-optimized images adversely impacted performance by increasing page load times, consuming more bandwidth, and diminishing the overall user experience due to larger file sizes and slower rendering on the website
• Database Server in the Wrong Availability Zone: We found that the client’s database server was hosted in the wrong region leading to unnecessary latency for customers, causing delays in data retrieval and transaction processing. This geographic misalignment resulted in slower response times, impacting the website's overall performance and user satisfaction.

Our Action:

• Upgrade nopCommerce to Later Version: We upgraded the nopCommerce version from version 4.20 to the latest 4.60 version. Upgrading from nopCommerce version 4.20 to the latest 4.60 version resulted in a substantial performance boost, harnessing the advancements offered by .NET 7. The migration brought about notable feature enhancements and performance optimizations introduced by nopCommerce in its 4.60 release, contributing to a more efficient and powerful online store.
• Use of Old Version of nopCommerce The client was using nopCommerce version 4.20. The use of the outdated version of nopCommerce contributed to significant performance issues, as older versions lack essential updates, security patches, and optimizations, hindering the website's speed, functionality, and overall user experience
• Cleaning Junk Data from the Database in Generic Attributes, Categories, Products, and Manufacturer Table: We removed redundant or obsolete data from the database, specifically in generic attributes, categories, products, and manufacturer tables, contributing to enhanced performance. This cleanup process ensures a more streamlined and efficient database structure, reducing unnecessary load times and optimizing overall system responsiveness.
• BOT Restriction: In order to mitigate bot registrations and spam, our team developed an anti-bot registration plugin. This plugin utilises IP-based blocking to detect and block bot registration attacks on the site, enhancing security and helping to mitigate spam.
• Brought Source Code Modification to Plugin: We have converted the direct source modification in the older version of the project into plugins in following a development approach that improves the performance of the application.
• Query Optimization: Used Tempt Table to join query with product table instead of running WHERE / IN query for a list in the product table.
• Implementation of Caching: Implemented proper caching where required.
• Database Index: Include some Database Index to optimize the query performance.
• Image Optimization: By implementing the WebP image format and addressing the presence of unoptimized images on the site, we successfully mitigated performance issues caused by larger file sizes, slow rendering, and extended page load times. The adoption of WebP, along with the identification and optimization of weighty images, significantly improved bandwidth efficiency and enhanced the overall user experience by ensuring faster and more streamlined content delivery.

The Outcome:

• Lighting Fast Page Load Speed: After optimization, the site's pages take less than a second in regular site visiting hours and not more than 5 seconds in extreme pick-hours.
• Precise BOT Protection: The site now can detect most of the bots and handle them accordingly as a search engine customer instead of creating new guest customers.
