Hi,
I'm trying some apache benchmark and I saw very bad things.
I'm currently migrating my website (+300k page viewed per month) from old
version (simple php with mysql) to new one that will use Zend Framework and
PostgreSQL.
I don't understand why I'm having this result using apache benchmark:

You can view the new page here:

I thought to some design problem, but I reviewed the code and I didn't see
any strange. Anyway all is cached, and there is no query performed. I got a
grade A with Yslow too. So I continue to don't understand.
I'm scared that I could have problem when I will go online with the new one.
Do you any idea about it?
Thank you!
