I timed time required for creation of an anchor database,
when it was the case where GTAGSCACHE is 5000000, and 50000000.

-------------+----------------------------------------------
             |             format of tag files
 GTAGSCACHE  |   standard       pathindex        compact
-------------+----------------------------------------------
   5000000   |    74min           68min           75min
  50000000   |    33min           30min           23min
-------------+----------------------------------------------

Although GTAGSCACHE has big influence on the performance of htags, 
it has appeared only in the manual of gtags.

I think that the section which described the following thing needs to be added 
to the tutorial.
 o Which operation is influenced by the value of GTAGSCACHE at performance
 o How to determine the value of GTAGSCACHE
