Comment(by markjaquith):

 On my live blog, with a whole bunch of plugins, a 75 page menu with crazy
 hierarchy (up to the max depth allowed) only takes 18 MB at its peak. A
 brand new blank menu peaks at 3.65 MB. A twenty member menu uses 5.53 MB

 All these numbers are {{{memory_get_peak_usage() / 1024 / 1024}}} in
 {{{admin_footer}}}, on a save of the menu. Displaying the menu takes a
 little less.

 Hierarchy doesn't affect it to any significant degree.

 I'm guessing Aaron's install is already using a significant amount of
 memory as a base, or that he has a plugin that is somehow intensifying the
 memory usage of the menu code.
