blog.jsp jahia4.1.1 abysmal performances

Hello,

I wish to add pages with very close functionalities to the blog.jsp template
in on of my intranets, unfortunately while using corporate_portal_templates
performances are catastrophic!

From the logs:

'Other' pages (pid 16, 18, 221) are processed between 125ms and 400ms.

But the page using blog.jsp as template (pid 320) can't seem to be below
80000ms ! 200 slower!

Do someone has a clue or a way to further debug this, because I definitely
can't use it that way.

Best regards,
Nicolas
