Web Page Profiler for Component Display Timing Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tools fail to effectively identify and isolate performance issues causing slow web page display on client data processing systems, as they do not provide necessary information when problems are non-reproducible and are influenced by various factors such as server response time, traffic, and browser issues.
Innovation Solution
A profiler integrated into the web page that identifies components and measures display times within a graphical user interface, creating a profile to help identify corrective actions that enhance display speed by analyzing client-side and server-side processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current profiling tools are used to capture web page display information, then step-by-step process information can be obtained, but the tools fail to provide needed information when problems are non-reproducible and cannot effectively identify performance issues
Solution Approach 1:
The profiler embeds timing instrumentation code within the web page itself before the page is delivered to the client. This preliminary action ensures that timing data is captured at the source, allowing accurate measurement of component display times even for non-reproducible issues, as the measurement mechanism is already in place when the page renders.
Solution Approach 2:
The patent introduces a profiler as an intermediary component that sits between the web page content and the display system. This mediator captures timing information from various components (images, scripts, CSS) and aggregates it into a comprehensive profile, enabling accurate identification of performance bottlenecks without requiring reproducible test conditions.
2Measurement precision
If detailed timing information for all web page components is collected, then accurate performance analysis is achieved, but the complexity of the profiling system increases
Solution Approach 1:
The profiler divides the web page into distinct components (images, scripts, CSS stylesheets, HTML elements) and measures timing for each segment separately. This segmentation allows precise measurement of individual component display times while keeping the measurement approach simple and modular, avoiding the need for a monolithic complex system.
Solution Approach 2:
The web page itself serves as the profiling mechanism by embedding timing instrumentation code within its own structure. The page's own components generate and report their timing data, eliminating the need for external complex profiling tools. The page profiles itself, reducing system complexity while maintaining high measurement precision.
3Loss of information
If the profiler collects timing information for all components including metadata processing, then complete performance visibility is achieved, but the time required to profile the web page increases
Solution Approach 1:
The profiler operates continuously in the background as the web page components are naturally processed and displayed, rather than interrupting the process to collect data. Timing information is captured continuously during the normal rendering flow, ensuring complete performance visibility without adding significant profiling overhead, as the measurement occurs during the actual useful action of page display.
Data Source
AI summary
A method, computer system and computer program product for profiling a web page. Components in the web page are identified. Times to display the components for the web page in a browser in a graphical user interface on a display system for a client data processing system are identified while the components are processed for display on the display system during use of the application by a customer. A profile of the times is created to display a group of the components on the display system when a user input from the customer requests information about the times to display the group of the components, enabling identifying a corrective action that increases a speed at which the web page is displayed on the display system for the client data processing system.
