[opencms-dev] Bad performances problem with queries in the database

[Joe Desbonnet]

It's my understanding that hits from Flexcache are served from memory
with zero DB activity.
What is your template's cache property exactly?

On my templates I have
"uri;element;params=(print,accessible);timeout=60" on the template
JSP.

BTW: on a related topic: has anyone tried the Cache option in Apache's
mod_proxy? I wonder what are the pros/cons of caching at the Apache
end vs Flexcache. Any comments?

Joe.
