If you don't go with counterCache you might want to adjust the
contains array so that you're only fetching the ID for each comment.

$posts = $this->Post->find(
'all',
array(
'contain' => array(
'Comment' => array(
'fields' => array(
'Comment.id'
)
),
'Tag'
)
)
);

This way, you're not fetching a bunch of unnecessary data and you can
use sizeof() to get the number of comments for each post.
