As mentioned previously by eupos, you need to:
1) Change the default_mh_post option (Setup => Defaults). This option is used for guests and users who have an invalid user_default_mh_flatpost value.
2) Change the user_default_mh_flatpost default value. This is what new users will get set as their posts per page. Instead of executing raw SQL queries to change this, I'd recommend using the database editor. However, gforum's default columns are marked as un-editable from the database editor (so things aren't inadvertently broken), so you have to manually enter the url:
http://example.com/path/to/admin/db.cgi?db=User&do=editor_columns&modify=user_default_mh_flatpost
From here, you can change the default from 25 to whatever you want.
3) Although I don't suggest you do this, you can also change the default for your existing users. Just follow the instructions from above.
The same applies to the other columns like default_mh_forum/user_default_mh_forum, etc.
