While an obvious point, it's also worth mentioning that you're not
doubling the entire site's load. The goto and the second call to
Drupal only happen on form-posting activities, and the page content
isn't downloaded the first time round. So while Drupal is getting
built up twice, the expensive part of sending out the page request
only occurs once.
I know that you know this, but it helps to think of things in a cost/
benefit mindset. Most sites are read-heavy, so the redirect only
occurs on a very small percentage of requests. Even an active site
will see less than 1 post for every 500 views, so creating a 501th
request is well worth it to reap the benefits already discussed in
pajunas interactive, inc.
