Slow WLST script

[lhg1]

Hi

I have a wlst script that is very slow. It can take over 1 hour to run.

It is collecting IdleThreads.
We have a Dashbord that collects the same, and running a lot quicker.

Can any body tell me how to optimize the script.
It is running like this.

./wlst.sh scripts/MonitorThreads.py environments/middleware_domain/online

export BEA_HOME=/appl/bea
export WL_HOME=$BEA_HOME/weblogic816

export JAVA_HOME=$BEA_HOME/jdk142_11

LIB_BASE=.

export JYTHON_HOME=${LIB_BASE}/common/jython/

CLASSPATH=

CLASSPATH=$CLASSPATH:${LIB_BASE}/common/jython/wlst.jar
CLASSPATH=$CLASSPATH:${LIB_BASE}/common/jython/jython.jar
CLASSPATH=$CLASSPATH:$WL_HOME/server/lib/weblogic.jar
CLASSPATH=$CLASSPATH:$WL_HOME/server/lib/wli.jar

PATH=$PATH:${JAVA_HOME}/bin:${WL_HOME}/server/bin


export CLASSPATH
export PATH

export WLST_HOME=${LIB_BASE}/common/jython

export PYTHON_PATH=${LIB_BASE}/common/jython/lib
CACHE_DIR=/var/tmp


${JAVA_HOME}/bin/java -classpath ${CLASSPATH} -Dpython.cachedir=${CACHE_DIR} -Dpython.home=${JYTHON_HOME} -Dpython.path=${PYTHON_PATH} -Dweblogic.wlstHome=${WLST_HOME} weblogic.

Who knows. I'd add timestamp traces to see where the time is going
