Profile JavaScript* and Flash* Code
New profiling support in emerging internet browsers and other script-oriented products allow developers working with new JavaScript* or Flash* JIT technologies to analyze their code. Use the VTune analyzer to optimize for scalable performance of these codes on Windows* and Linux* to ensure the best end user experience with your application. VTune analyzer supports profiling JIT’d code when browser vendors add the required support. This enables deep performance analysis of these additional languages:
- JavaScript / AJAX
- Flash (Action Script)
Check with your browser supplier for details on when their browser will enable support.
Profile Dynamically Generated Code
Many applications today emit their own runtime-generated or just-in-time (JIT) code. New profiling APIs in the VTune analyzer enable performance analysis of dynamic code and allow you to view annotated source code directly from the analysis results.
Access to VTune Analyzer’s Open Data Model
VTune analyzer can now support many different software platforms with performance sampling analysis. Use the new open data model APIs to combine the VTune analyzer's powerful GUI on Windows* or Linux* with data from your custom collector to analyze any application on a wide range of platforms.
- Collect data on operating systems not directly supported by the VTune analyzer.
- Supported Windows* Operating Systems
- Supported Linux* Distributions
- Collect data on embedded Intel hardware based platforms.
Access to the latest Experimental Technologies
VTune analyzer users have access to the latest experimental performance tuning technologies Intel has to offer. Visit whatif.intel.com and look for Intel® Performance Tuning Utility and Intel® Platform Modeling with Machine Learning. These tools include a number of exciting capabilities including:
- Statistical Call Tree - profiles with low overhead to detect where time is spent in your application
- Basic Block Analysis - displays hotspots with basic block granularity and generates a control flow graph for advanced analysis of application, even without the source code
- Data Access Profiling - identifies memory hotspots and relates them to code hotspots
- Dependency Plots - visualize the relationships between metrics
- Event Rank - view the list of best predictors of performance using machine learning
