BIRT 3.7.1 and Actuate XLS emitter

Migrateduser

<p>We have BIRT 3.7.1 installed.  Performance on XLS exports is pretty slow.  I see that what happens is a relatively small XLS document turns into a huge XML file during creation, which then seems to eat up all the memory on our server.  Is there a difference between the open source XLS emitters and the Actuate XLS emitters?</p>
