[wp-forums] Codex: Using Permalinks

[Otto]

Apache doesn't do the matching, WordPress does.

And no, it is not a good idea to start the permalink string with
postname, category, tag, or author. Doing so will turn on the
"use_verbose_page_rules" flag, which will create extra matching rules
for the Pages in the system.

Basically, when you have something at the top level like this, it
needs to create one-rule-per-page in order to detect the Pages
properly. Without these at the top level, it can use
one-rule-for-all-pages to match against.

It's generally not a big deal unless you have lots of Pages. But if
you do, and you start the permalink string with one of those, you can
create a big slowdown due to the excessive need to search the Pages
for every URL.
