[jira] Created: (VELOCITY-450) Why Velocity Templates takes larger
memory
Why Velocity Templates takes larger memory
------------------------------------------
Key: VELOCITY-450
URL: http://issues.apache.org/jira/browse/VELOCITY-450
Project: Velocity
Issue Type: Bug
Components: Source
Affects Versions: 1.4
Environment: Windows 2000, Jdk1.4.2, Tomcat4.1.29
Reporter: coumaravel
Priority: Blocker
Hi,
We are using the velocity templates extensively to
generate HTML reports. Normally our templates size on
the Disk is around 20-50kb, when it gets loaded into
Application(Tomcat) memory it turns to 3-5MB.
As of now we have 500 templates, in near future we are
planning to increase this to 1500.
Any Idea why this is happening. Any help in this is
much appreciated, as this is becoming a bottleneck for
the scalability of our application.
Thanks in advance.
Regards,
Coumar

Posted by Erron Austin <er...@gmail.com>.
Also, my application uses many templates (>500) and it uses hardly any
memory. I'm able to confirm this using yourkit. Granted my templates
are not macro intensive.

Hello,
Are there any updates regarding issue?
There seems to be almost no development activity in Velocity community.

[jira] Updated: (VELOCITY-450) Reduce memory usage for Velocity

Posted by "Nathan Bubna (JIRA)" <ji...@apache.org>.

Nathan Bubna updated VELOCITY-450:
----------------------------------
Summary: Reduce memory usage for Velocity templates (was: Why Velocity Templates takes larger memory)
Issue Type: Wish (was: Bug)
Priority: Major (was: Blocker)
Hi Coumar,
I've recently been talking about ways to reduce memory usage with someone else on the user list. I've add the highlights of that conversation to the VelocityFAQ:
See http://wiki.apache.org/jakarta-velocity/VelocityFAQ
If you have further questions about it, feel free to ask on the velocity-user@jakarta.apache.org list.
peace,
nathan

I'm guessing this has largely been dealt with via a number of different changes since 1.5. Does anyone still see this as a problem?

Hi,
I fixed something in https://issues.apache.org/jira/browse/VELOCITY-570. But I don't know if this helps for your problem.
So there is development activity.
Can you generate and analyze memory dumps of your problem? It is very nice to know what classes are holding what objects which use the memory.
Ronald.
