BCI Filters Configuration
|
BCI package filter was enhanced.
This filter allows configuring packages that are instrumented by BCI. The filter now supports interaction with BCI filter sets.
|
|
CPU View High level grouping of elements
|
Support of high level grouping within CPU views was implemented.
This feature will dramatically reduce the deepness of call stacks in the tree viewers.
The following element groupings were introduced:
-
Group deterministic sequences of method calls into the single node
-
Group methods from the same package under a single parent node
-
Group methods with low cumulative times under a single parent node

CPU Filter Enhancements
|
CPU View filters were enhanced in the following ways:
CPU View package filter was enhanced.
This filter allows configuring packages and classes that are shown in
the CPU snapshot views.
The filter now supports both exclude-only and include-only policies, as well as configuration
from predefined profiler filter sets or the workspace.
Profiling filter sets were introduced. This feature allows
the user to save filters in named filters sets.

Triggers
|
|
CPU Profiling triggers wa
|
Profiling triggers allow the profiler to automatically react to certain events in the JVM and perform a number of profiling-related actions.
Profiling triggers may be installed by performing right click on the Java editor ruler and selecting
the Toggle Profiling Trigger menu item:
Then trigger may be configured using the Trigger Properties property page which also may be accessed from
the Java editor ruler.

Profiling API
|
The
Code Pro Profiling API is contained in /plugins/com.instantiations.jvmti.agent/agent.jar in your CodePro Profiler installation directory.
Call static methods of com.instantiations.profiler.api.Profiler
class from your source code to influence the run time behavior of CodePro Profiler.

Agent Controller Enhancements
|
Current release includes numerous improvements and bug fixes in agent controller code.

Performance Improvements
|
Highly optimized algorithms were implemented in most
computationally intensive parts of profiler. This allows profiler to
operate much faster and consume less memory.
We have performed benchmarking of CodePro Profiler and newest versions of YourKit and JProfiler using benchmarks from SpecJVM2008.
We have configured all profilers to have the same filters before benchmarking.
The results are following (bigger score means better performance, less profiling overhead)
