OPS performance problem

Hi.

I use OPS to develop a B/S Application. Then, I have a performance problem: The Application is slow, slow...

The Application argument is that:

1. Record number: 30;

2. Filed number of each record: 40; (so, there are 1600 xforms:input or select)

3. Total Time: 20s

4. OPS init Time: <1s

5. Generator Busniess-Data: 2s

6. XForms epilogue.xpl and others: 17s

7. XForms Page Size: 40k

8. Generated HTML Page: 660k

9. Client and Server machine configuration, CPU: AMD 2000+ 1.5G, Memory: 1G

Throw a exception: java heap overflow, when open twice or third that page.

This perforance is badly. Is this OPS performance problem? Or, I can not use OPS with this method?

Re: OPS performance problem

How much memory are you allocating to the VM? If you're running out of memory you may just need to increase the VM size.

Also the very first time the the epilogue runs, there's a fairly noticeably delay which you don't see for subsequent requests (for any form).

Finally, 1600 inputs is a very large form! Bigger forms will be slower to display. Are these inputs really all on the screen at the same time?

Where do I find the 3.5 package ?

And what app server is best off JBoss and Tomcat ?

Re: Beta

Øystein,

use a nightly build instead:
http://www.orbeon.com/ops/doc/integration-development

JBoss is a fulll-fledged J2EE server and Tomcat is just a servlet
container, so comparing the two is a bit like comparing apples and
oranges. The answer is, it depends on the technology stack you choose
for your application.

Personally, I prefer Tomcat over a J2EE server:
1. Tomcat is a much smaller container/application than JBoss, and less
complicated.
2. Many features found in the J2EE technology stack, can also be found
in the Spring framework (http://www.springframework.org/) + Hibernate.

Hope this helps.

Henrik

Orbeon Forms 3.5 is not out yet. We have a milestone release, 3.5 M1,
which is available from here:

http://forge.objectweb.org/project/showfiles.php?group_id=168

Or, you can use a nightly build:

http://forge.objectweb.org/nightlybuilds/ops/ops/

> And what app server is best off JBoss and Tomcat ?

As Henrik explained, unless you really need JBoss, use the more
lightweight Tomcat.

1600 inputs fields is quite a lot for a single page. Still, 17s is
very long!

First, check this page:

http://www.orbeon.com/ops/doc/integration-tuning

Check your Java heap and make sure it is allowed to grow to a
reasonable size (500 MB, 1 GB). If your network bandwidth is small, be
sure to enable gzip compression in your servlet container or web
server. Use something like JMeter and make sure your VM is warmed up
before gathering numbers.

Are all the controls visible at the same time? We have recently been
working on an optimization for non-relevant controls which you can
enable with a property in recent builds:

<property as="xs:boolean" name="oxf.xforms.optimize-relevance"
value="true"/>

Also try to reduce slightly the XPath cache, for example:

<property as="xs:integer" name="oxf.cache.xpath.size" value="600"/>

Finally, you may have to run a Java profiler to figure out where the
time is spent.
