 This parameter is ignored when @option{-funit-at-a-time} is not used.

 @item large-function-growth
 Specifies maximal growth of large function caused by inlining in percents.
 This parameter is ignored when @option{-funit-at-a-time} is not used.
-The default value is 200.
+The default value is 100 which limits large function growth to 2.0 times

 @item inline-unit-growth
 Specifies maximal overall growth of the compilation unit caused by inlining.
 This parameter is ignored when @option{-funit-at-a-time} is not used.
-The default value is 150.
+The default value is 50 which limits unit growth to 1.5 times the original
