As of September 10th 2012, the "Drupal Groups team" has deleted our "Large sites and scalability of size", accompanied with the note Note: "Such a group already exists. Join the discussion in http://groups.drupal.org/large-scale-drupal-lsd-projects-and-plans".

I don't think that the LSD group is appropriate to discuss scalability and performance issues of existing Drupal versions (like D6), but whatever, some (anonymous) content moderator has made this decision. I can neither locate the existing content of the old group, nor the group's description (which included a distinction from exisiting groups), so apperently we need to start from scratch.

In a nutshell, "Large sites and scalability of size" dealt with scalability problems of Drupal core and popular modules from contrib that arise when Drupal sites reach a certain size (number of nodes, number of taxonomy terms, etc.); an increasing size of Drupal-based sites is usually accompanied by an increasing memory footprint, and that results in an increasing amount of fatal PHP errors (WSOD) if not somehow trageted. Since many of us are stuck with D6 for various reasons, the old group was mostly focused on scalability issues of "large" and "old" legacy sites (like the memory footprint of taxonomy_get_tree()) that might have resolved or mitigated in more recent Drupal versions.

In the past months, we found a number of workarounds to keep larger Drupal sites more or less manageable (e.g. gielfeldt's Taxonomy Edge module which provides overrides for the core Taxonomy module in regard to taxonomy_get_tree() and taxonomy_select_nodes(), while others have started to rewrite certain parts of Drupal core). Whatever the that of these initiatives is or was, it seems that this group will be our new home, so welcome back ;)
