The Challenge

Legacy Sitefinity Project with Severe Performance Issues Causing Website Instability After Content Changes

Website Becoming Unresponsive After Backend Content ChangesThe client's legacy Sitefinity project suffered from severe performance issues causing the website to become unresponsive - and sometimes go completely out of order - whenever content editors made changes on the backend. The instability made the platform unreliable for both editors and end users.Fundamental Architectural Problem with .Net Website ConfigurationInvestigation revealed that the website had been built as a .Net Website rather than a Web Application, causing unnecessary recompilations every time content was served. This architectural mistake was a root cause of the performance degradation and required migration to resolve properly.Unoptimised Code, Unused Scripts, and ORM-Related IssuesThe codebase contained critical performance bottlenecks in key methods, unused scripts adding unnecessary overhead, and complex issues related to Open Access - the Sitefinity ORM - that were contributing to the overall instability and slowness of the platform.
The Solution

Performance Analysis, Web Application Migration, Caching, and Code Optimisation

Comprehensive Performance Analysis and Code OptimisationEveliko conducted a thorough performance analysis of the legacy project, identifying and optimising critical methods through code review and performance tuning. Significant speed improvements were achieved by targeting the most impactful bottlenecks in the application's codebase.Migration from .Net Website to Web ApplicationThe project was migrated from a .Net Website to a proper Web Application, eliminating the unnecessary recompilations that had been degrading performance. This architectural change enhanced scalability and reduced the overhead required to serve content to users.Script Cleanup and Codebase StreamliningUnused scripts were methodically identified and removed, reducing unnecessary overhead and producing a leaner, more efficient codebase. This contributed directly to improved application agility and faster response times.Cache Implementation for Critical ModulesCaching was implemented for performance-critical areas of the application - most notably the pricing module - reducing repeated processing overhead and ensuring faster, more reliable delivery of key content to end users.Open Access Issue Resolution and Daily Collaborative SyncComplex issues related to the Web Application and Open Access ORM integration were identified and resolved. Throughout the project, daily sync sessions were maintained with the client to ensure transparent communication, swift issue resolution, and continued alignment with project goals.
