The default behaviour of Java is to compile all code to MI which is
extremely slow in the startup phase.

Additionally Java programs often require more memory than other
programs so they need larger memory pools.

Please also check that the DNS information is setup correctly. You
should be able to ping "google.com" and the name the machine thinks it
has without any delay in looking up the name.

Hi,

if you would run it on a 7 years old intel box with less than 1 GigaHertz it
won't run much faster; putting it to a recent intel box with about 4 times
more power (and plenty of memory) compared to the older intel box, it will
run much more faster.

After first startup of Tomcat and BIRT I have opened testreport.
When report is generated I closed the browser and again call the
test reprot. First time Tomcat need to load required jars but next time
it has them already loaded so it should be faster but it is not.
Maybe little but this is unacceptable.

Tomcat is running in its own subsystem with 512MB pool size which should be
ok.

DNS is ok.

I have tesetd BIRT on 2processor XEON PC and it is also kinda slow in
report generation?!?!? Maybe for one user is ok, but if this is aimed to be
used on
the system with about 250 users, speed of BIRT is unacceptable.

Not Intel...AS/400 (iSeries) models 520 (1y. old) and 810 (3y. old).
810 have a lot of horesepower ) but I am not impressed with BIRT speed.

Niko.

Hi,

the processor of the 810 is about 7 years old and comparable to an intel box
< 1 GigaHertz. The 520? it depends on, wether it has a power 5 or a power
5+ and it might be restricted by software (they call it on demand...). it
should be no problem to put the tomcat to a + 2 GHertz Intel and same with
BIRT and I would bet, it would be much faster!!!

In that case another approach might be a good idea.

What is it you need to do?

Sorry to stray the thread, but does anybody know if you can run BIRT
outside of a servlet engine? I have only seen reference to it from a
servlet engine context, but if you could make it run in a batch job in
i5OS you could have RPG programmers create some nice looking reports
from their native language.

I have done something similar with my open source RPG Chart Engine
(http://mowyourlawn.com/RPGChartEngine.html) and am looking to do it
with BIRT but haven't taken the dive into the product to learn how it
works.

Thanks,

For now we are trying to find most felxible solution for graphical
reporting.
As BIRT is Java it seems to be a good start but as I have said it is to
slow.

We are testing some SQL Querys with output to table and then conencting
with BIRT to that table to create graphical reports.

Those are some statistical data for managers but in the future it my be used
for
other or maybe all of our reporting.

Niko.

It is possible, there is a lot of programming examples on BIRT web site.
You can programatically do whatever you wish with it.
I have done some tests and successfuly created final reports on disk without
servlets.
(done it on PC, not on iSeries). Results can be in PDF or original format.
