Managing Performance of Drupal when in Maintenance mode
One of my sites runs behind two Varnish dedicated servers with something like 12 web servers running Pressflow 6 and four MySQL full InnoDB database servers. This more than handles the load the site runs on.....until.....I put it into maintenance mode.
At this point Varnish stops caching the pages as they aren't sending HTTP 200.
The load average on the Apache/PHP boxes shoots very quickly to above 100 and in general the boxes are looking for cliffs to jump off.
I'm wondering what others do about this.
I think these are some options.

Putting a Drupal site into maintenance mode using Drush 3.0
I saw someone post to how they run a custom SQL script to put a Drupal site into maintenance mode using Drush's SQL commands, but here's the easier way without any SQL code necessary. Using Drush 3.0 we can turn a site on and off in a split second using the following command:
drush vset site_offline 1
To turn the site back online we run the same command but change the 1 to a 0, like so:
drush vset site_offline 0
*To learn more about the VSET command for Drush just type: drush help vset
