Hi.
I need some advice about performance on an application I'm actually writing.
Some days ago I saw a lot of message speaking about performance.
I understood there is problems with :
- freemarker :
by adding a freemarker.properties file in classpath with something like
template_update_delay=3600
freemarker should cache compiled template for one hour.
But: I saw a message saying that freemarker doesn't cache template
that come from classpath.
I tried but, for me, all template are correctly cached. No
re-compilation occur.
Do I missed something ? Is there any other performance issue with it ?
- ognl :
ognl seems to be slow when there is method call.
I made some tests and yes, it's very slow : on my PIV, 3Ghz, each
call to getText() take approximatively 200ms.
Of course, i18n reloading is disabled.
Is there a plan to fix this in 2.0.x branch ? At least, is there a
way to fix it ?
I saw that there is a proposal to make switchable expression
languages (http://jira.opensymphony.com/browse/XW-461) but there is no
schedule.
without method calls, ognl is "relatively" fast but not so much :
between 0 to 15ms by statement.
I'm using 2.0.1.
I tried to upgrade to 2.0.5, but I stopped because it don't work out of
the box. I'll try later ...
So do you think I'd should for now
- try again 2.0.5 because there is fixes in it ?
- remove all getText() called in jsps ? (not always possible ...)
- no solutin before 2.1.x ?
- anything else ?
- help you ? how ?
Thanks for your time.
Mike
