Description

Description:
Symptoms
========
BW Runtime :
1.For projects that use security policies from the policy palette, the engine startup time is longer than before
2.There is an out of the box performance degradation issue on windows platform

BW Design-time :
1.For any of the shared connection resources like JMS connection, JDBC connection, FTP connection etc, when you type in a password, there is a considerable delay


Impact
======

Slowness of engine during startup time


Workaround
==========
BW Runtime :
1.Though the engine startup time is longer than before, JRE 1.5 actually improves performance as the engine continues to run for longer periods
2.For out of the box performance degradation issue on windows platform use the following performance flags in bwengine.tra file :
java.extended.properties -XX:+UseBiasedLocking -XX:+UseSpinning
If you already have any existing properties, you can append the above properties to your existing properties

BW Design-time :
1.Delay during entering the password is only for the first time. The next time you re-enter the password or enter a password for another shared connection, you will not see the delay



Cause
=====
The security libraries are taking a longer time to initialize with JRE 1.5. This was not the case with JRE 1.4
