The function
expand-generation-1
controls the subsequent behavior of the garbage collector when insufficient space is freed by a mark-and-sweep. When this occurs, either generation 1 is expanded, or the objects in it are promoted.
If
on
is
nil
, generation 1 is never expanded.
If
on
is
t
, generation 1 is always expanded (rather than promotion) when needed.
If on is 1, generation 1 is only expanded if its current size is less than 500000 bytes. This is the initial setting.
expand-generation-1
is implemented only in 32-bit LispWorks. It is not relevant to the Memory Management API in 64-bit implementations, where you can use set-default-segment-size.
