garbage collection not reflected in the nmon
i have my application running on AIX box (configuration given below)
My application does garbage collection pretty well, as such the memory free shows 500 MB - 700 MB freed up in the log statements printed in the application, but the nmon shows the physical space going upwards and does not reflect the garbage collection that was done. What could be the reason ?
Configuration..

1900 - MHz CPU clock rate

otest(1) BSD General Commands Manual otest(1)
NAME
otest -- SenTestingKit, OCUnit.
SYNOPSIS
otest [-SenTest Self | All | None | <TestCaseClassName/testMethodName>] path
DESCRIPTION
otest runs the unit tests found in the bundle given at path.
ARGUMENTS
-SenTest value This flag denotes the scope of the unit test to be run. Possible values are Self, All, None and <TestCaseClassName/test-
MethodName>. The default value is Self.
path Path to the bundle that contains the unit tests.
OBJECTIVE-C GARBAGE COLLECTION
otest is built with support for Objective-C garbage collection. Due to the "whole process" nature of Objective-C garbage collection, invok-
ing otest from the command line or an IDE or debugger will run otest with garbage collection enabled. Doing so requires that the bundle con-
taining the unit tests also be built with support for garbage collection.
To avoid this requirement and disable garbage collection, run otest in an environment with the OBJC_DISABLE_GC environment variable set to
YES.
ENVIRONMENT
OBJC_DISABLE_GC Set to YES to disable Objective-C garbage collection for otest when running test bundles that do not use it.
FILES
/Developer/Tools/RunTargetUnitTests A script that calls otest with the correct arguments for use with Xcode.
