I'm currently looking at different reporting engines to see which one we
want to implement. BIRT looks really good! I have a couple questions that
I can't find answers to on the website.

How does the ReportEngine perform under heavy usage? Can one ReportEngine
instance run many reports simultaneously?

Floor,

We have load tested BIRT engine with varying report characteristics. The
BIRT Report Engine scaled well with the number of data controls, the number
of rows in table, the number of columns in table and the number of
mathematical aggregation in the reports. We also found that the performance
scaled well with faster CPU speed and with additional number of CPUs in the
machine.

Yes, one ReportEngine instance can run many reports simultaneously. Our
tests submitted concurrent requests to Report Engine deployed on Tomcat to
run many (up to 50 in our test) reports at the same time. The birt engine
was fairly stable and was able to leverage all resources on the machine when
loads increase until the machine's hardware limit is reached.
