Distributed App Profiling via Client-Server Timestamp Correlation

The patent applies preliminary action by instrumenting the code during the unified development phase, before distribution. Timestamps and markers are embedded in the code at key points (method entries, exits, network operations, database operations) during the initial development stage. This preliminary instrumentation ensures that performance data collection is already in place before the code is compiled and distributed to different tiers, eliminating the need for post-distribution instrumentation and enabling effective performance tracking despite the obscured code connections.

The patent uses markers and timestamps as visual indicators (analogous to color changes) that are embedded in the code at specific locations. These markers maintain their identity through the compilation and distribution process, allowing traceability of code execution flow across tiers. The markers act as persistent identifiers that preserve the connection between original code and its distributed counterparts, enabling performance analysis despite the transformation and separation of code across multiple tiers.

The patent segments the page update process into multiple parts: initial HTML retrieval, subsequent incremental updates via AJAX, and selective rendering. The instrumentation tracks performance at each segment (initial load, asynchronous updates, partial refreshes). This segmentation allows the system to maintain data consistency through structured updates while improving user interaction speed by avoiding complete page refreshes, as users can continue interacting with partially updated content.
