Conclusion


3/9

Intel VTune is software from Intel used by the development

companies to analyze their software's and applications

performance.

It also provides boost performance of applications, on specific

OS.

One can work with the VTune analyzer using the graphical

interface and command line interface.

The VTune(TM) Performance Analyzer can analyze the

performance of Linux applications, Java application and .NET

Applications.

Sampling is the process of collecting a set of datafor analysis and representing the analyzed data in a

statistical format.

Calculates the actual performance of an application

over a period of time and for various processor

events.

It monitors all the software executing on your

system including the operating system, JIT-compiled Java applications and .NET applications.

Sampling does not modify binary files or

executables.

It helps us to identify:- Hotspots and Bottlenecks.

TIME-BASED SAMPLING (TBS): - The VTune(TM) uses

the operating system timer to interrupt and collect samples of

all active instruction addresses at a regular time interval. The

collected samples provides the performance data of all theprocesses running on the system. Processes that took the

longest time to execute have the highest number of samples.

EVENT-BASED SAMPLING (EBS): - Use to identify

system-wide software performance problems caused by

processor events, such as Cache Misses and Mispredicted

Branches. From the EBS data, one can determine which

process, thread, module, function, and source line in program

generated the most processor events, and if any of those

events impacted the performance of program.
