+The option
+\family sans
+Maintain mostly
+\family default
+ is somewhat in-between the above two.
+ If this is selected, \SpecialChar LyX
+ will compile the whole document at the first output,
+ which sets up counters and references correctly.
+ In subsequent outputs, it will compile the whole document only if a change
+ has been made in an excluded child document.
+ As long as you only edit the included files, this approach is as fast as
+ the second one, while giving you more or less correct counters and references.
+ They are only more or less correct since the change of size of included
+ documents obviously also changes the pagination of excluded documents,
+ but this change cannot be tracked with this method.
