Error description

• Environment: Windows
  Product name: IBM? Rational? Business Developer
  
  Program Version    :  8.0.1.1
  Description.
  A  performance differential is observed after migration of
  applications from RBD v7.1.0.5 to RBD v8.0.1.1.
  
  The applications where this is seen include calls to a
  Webservice and are deployed on various WebSphere server versions
  and when the v7.1.0.5 project is imported into RBD v8.0.1.1 the
  migration wizard does not report any errors.
  
  After then deploying the application and running the front end
  jsp the application performance can be measured as taking up to
  four times longer then was seen in RBD v7.1.0.5 to complete the
  associated iteration operations.
  
  The same results are seen after regenerating the EGL source code
  for the application and also with the upgraded RBD
  8.0.1.2.version.

  SOAP Service invocations on Websphere are slower when
  generated in 7515 and 8011 than they were in 7105.
  

Problem conclusion

• We were creating a new run unit for new EGL record instance.
  I changed the code to create 1 run unit per thread and use
  that for each record instance.
