In response to performance concerns, a thorough health check uncovered the need for optimization across scripts and custom solutions. Key measures included:

-Refactoring code for efficiency.

-Minification of JavaScript (JS) and Cascading Style Sheets (CSS) files.

-Implementation of diverse compression techniques.

-Reconstruction of select solutions to streamline performance.

The homepage hosted various web parts spanning Alerts, News, Videos, RSS Feeds, Stocks, Survey Charts, My Links, and Countdown, contributing to prolonged load times. Remedial actions comprised:

-Image and thumbnail compression in sections like Alerts, News, and Videos.

-Replacement of the stockticker.js script with the Yahoo! Finance REST API for the Stocks web part.

-Redevelopment of custom web parts (e.g., My Links, Countdown, and Survey Charts) to optimize performance.

For real-time data updates in Survey Charts, a data storage form was devised, enabling retrieval and presentation through JavaScript Object Model (JSOM). Additionally, users could visualize charts in bar or pie form via the jqPlot jQuery plugin.

To expedite page loading, the Countdown timer for new events was segregated from the homepage using a jQuery plugin.

Adherence to coding best practices and effective compression techniques led to significant reductions in page load times, culminating in a lighter and swifter portal for user interaction.

The improvements in performance and load times led to enhanced user engagement and increased utilization of ZS Pharma’s Intranet Portal, thereby validating the return on investment (ROI) in SharePoint Online and Office 365.
