[support] Performance: is better a node_load or a direct SQL query ?

[Pierre Rineau]

Note: you must care about the context your function is executed. If it's
an AJAX callback, you might want to do your own query, because there is
no way your node might be loaded twice.

But, if you are executing this function in normal Drupal execution flow,
you have to use node_load() because there is a lot of cases in which
your node will be loaded more than once (views, some custom blocks,
access checks on url, etc...).
